Cheap, but excellent-sounding early '70's Rotel receiver - RX-203A

Gang-Twanger

Resident Wharfedaliophool
I've realized over the last year or two that most of the receivers and amps that were made in the early to mid '70's sound excellent, in comparison to what has been made over the last 20 years. I've seen quite a few entry-level receivers from the early '70's that just smoke the majority of the new stuff - in terms of overall sound quality. A big part of it is that they're so-much-warmer-sounding than the new stuff. This is due in large part to the fact that back in the pre-"home theater" days, manufacturers weren't worried about "surround sound" and all the other "bells and whistles"-type stuff that you see today, and they were free to concentrate on the pre and power amps and the overall sound quality. Onboard phono preamps (which you hardly even see at all these days) were a much-higher priority back then, and they sound as good or better than many of today's outboard units.

Anyway, I stumbled onto a Rotel RX-203A receiver (from the early-to-mid '70's) while picking up a set of speakers that a guy was selling on Craigslist for $30 - While I was carrying the speakers out to my car, I happened to notice this dirty, beat-up, old Rotel unit sitting on top of a shelf, and when I inquired about it, the guy said "You want it? Take it." - and so I did. I had already purchased an NAD 3140 off Ebay to power the speakers I bought, so I shelved the Rotel until a later date. Then about 9 months later, I got the urge to drag it back out and hook it up to my speakers to see how it sounded. I was amazed to find out that this cheap-looking, little receiver (around 20w-25w per channel, I think) sounded WAY-better than the NAD that I had been listening to for the last 9 months. I couldn't believe the sound I was missing out on all this time. It sounds clear, yet warm and lively, and with a much-better soundstage than my 3140 had. So needless to say, I shelved the NAD, and the Rotel is pulling a quite-respectable backup duty until my Sansui 4000's left channel is up and running again.

Now, like I said, this is an entry-level model, as far as I can tell (from the fake vinyl paper-veneer and the basic look of the interior), and it seems to put out somewhere around 20w-25w per-channel. But even though I have to turn this up a lot louder than I had to with the NAD, the sound itself is much-better. So if one of you spots one of these units sitting in the Swap Shack at your local dump, I urge you to grab it and bring it on home with you. These make great backup receivers and would also be great for a simple bookshelf system on the cheap. There's not much to them, and they're not exactly "mid'70's Marantz"-pretty, however, I assure you that these sound very, very-good for an old, entry-level, low-wattage receiver. Two nights ago, I listened for 16 straight hours, and I loved every minute of it. I actually enjoy it more each time I listen to it. Between the Rotel receiver and the old Wharfedale speakers that I got from the same guy ($30 for everything), I'd say it was the best $30 I ever spent.

If you're ever looking for that warm and lively, early '70's receiver sound, but you don't want to pay more than a few bucks to get it, I urge you to check these out. Despite their entry-level looks, these things can deliver that warm, classic sound in spades (Sorry, I can't put up a picture - If I can find one online, I'll try and get that up).

I should also mention that the more-expensive receivers from the '70's RX line are also going for very-little money. The RX-803 and RX-603 are great examples - quite a step above the 203A in terms of features. You can't go wrong with any of these at the prices I'm seeing right now. Plus, Rotel has a line of excellent-sounding integrated amplifiers from the early to mid-'70's as well. They too are going for peanuts these days. IMO, these are some nice sleeper units.

Hopefully this won't cause this thread to get moved, but here is a photo link for a good shot of an RX-403 (a step up from the 203A). This isn't a link to an auction - It's just a link to an enlarged picture from an international auction, and not the auction itself.

I'm not sure if the link is even working (as I am having trouble with it myself), but their are plenty of pictures on the 'Bay of various receivers from the RX line (Check "international sellers).

Nice!

I got an RX-403 for very little last week and it is a great receiver! Here's the link to my thread with pictures. There is also a link to a site on which you can get Owner's and/or service manual for most Rotel gear.

Mine also looks sorta BOTL, but still, it's the bottom of a very fine line of products! The top unit, RX-1603 is a 180W beast! Check it out!

Enjoy!

Thanks for the links! The face on yours is in great shape. Does yours have the cheesy, vinyl veneer-paper like mine? It may not, as mine is a step or two below yours, but I'm telling you, this little thing (It really IS little) sounds great. Very-warm and lively-sounding. I'm trying to get my Sansui 4000 back on it's feet, but since I have this little receiver as a backup, I honestly haven't been in a huge rush to fix the other one (and that's good since I don't have the money to send it to a shop anyway - I'm trying to get it working myself, but I'm a total novice so it's not going well).

Looking at mine (even the inside), I would never have thought it could sound anywhere near as good as it does. Had I not needed a backup, I might never have tried it. Plus, it's incredibly-light - especially for a mid '70's receiver. It's very-deceiving. I DO have to give it a steady diet of electronics cleaner though - otherwise the highs on one side start to cut out a bit (enough to bother me). This thing was seriously-dusty when I got it, and then it sat for 9 months. Great-sounding little unit though. Warm, clear, and dynamic - Sounds beautiful with my speakers. I'm listening to the Barry Diament-mastered CD version of Zeppelin's "Presence" (It really makes those earlier, non-remastered '80's CD's shine).

What really kills me is that I spent $90 (Well, $110 if you include gas) on an NAD 3140 integrated amp, and I listened to that for 9 months while the Rotel sat on the shelf. The NAD just doesn't gel with my speakers the way the lower-powered Rotel does. I think it's got to do with the Rotel being from the early to mid '70's while the NAD is from '81-'83. They're just two totally-different sounds - One's warm and the other is "accurate". The Rotel honestly sounds clearer though, which I would have never expected considering it's entry-level status.

BTW, that RX-1603 is a beast - DEFINITELY a much-higher level of build quality than mine. I like the big dual heatsinks on either side. And it's got a huge toroidal transformer as well - VERY-NICE. I doubt they used the vinyl veneer paper on that one. Those things seem to fetch a lot more money than the other RX models though. I can't remember if it's 80w X 2 or 160w X 2. The latter wouldn't surprise me, considering how well they built that thing.

Regarding the RX-203A, I'm beginning to wonder if the "A" at the end might represent a less-expensive line than the regular RX line (without the "A"). I really don't know for sure, and there isn't any online info that explains those differences (although I haven't finished reading that Rotel promotional link). It DOES look like mine is a little older than yours, judging by the way the "case" wraps around the chassis. On mine, part of the "wood" surface is viewable from the front, unlike your RX-403 (If you view yours straight-on from the front, all you see is metal).

I read that Vintage Audio link, and the way the guy describes the listening test for the 1603 is exactly the way I would describe the sound of my little RX-203A (particularly in the way he describes the sound of vocals), so maybe it IS indicative of the entire RX line.

I'm listening to "Physical Graffiti" right now, and it amazes me how much distortion there is on Robert Plant's vocals. Apparently this is the way the master tape sounds. In the past, I used to wonder if there was something wrong with my system, but it really does sound that way. LOTS of "dirt" on those masters.

Thanks for the comments!

My 403 is in pretty good shape I'd say. The aluminium faceplate is very clean and pretty much scratchless. The chromed plastic bezel that surround the tuner dial display is a bit smudged, but I can live with that.

Unfortunately, mine too has the vinyl faux-wood cover over the cheap wood case. That alone almost made me not buy it, but I would have missed out on a great little amp.

Can we get a pic of your 203?

If it's up your alley, check the service manual and adjust the bias, the procedure should be well detailed. It might improve your sound if for some reason it's way off-specs.

I also have a similar experience to yours, as I bought a NAD 701 receiver (circa ~1995 IIRC) maybe a year ago, for 60$ with remote. I keep using it because of the remote. The ~30 year old 403 blows it away. The 701 sounds kinda dull and not lively, it's hard to describe really.

Enjoy!

A lot of those low-powered receivers in the 70's were sleepers. That is when manufacturers put as much quality on their BOTL receivers and amplifiers as their TOTL units.

Yeah, that kinda is how I feel about modern stuff. Nothing wrong with it basically, the real good stuff from back then is "as good" as the real good stuff we have now. It's the low-end stuff that really took a dive, but this is a natural process of market dynamics...

Hey Guys,

Fast forward about a year & I just found one of these today at a garage sale. The guy had a bigger Rotel & turntable hooked up. When I asked abput it he said that unit wasn't for sale (didn't realize until after asking that that one was his regular listening system) but he said he had a smaller one in the corner for sale. Walked over & found the 203. Must confess I knew nothing about it but figured for the $10 he was asking it was certainly an acceptable risk. He even still had the original owner's & technical manuals. I've only gotten a chance to fire it up & listen through the headphone jack so far but have to agree w/ everyone's opinions so far. Can't wait to hook up a turntable to it & see how that sounds.

Just picked up a Rotel RX-604 cheap myself- the inside build quality is excellent! Going to fire it up tonight...
 
I'm late to the party.
Tell me about it. I have a great 203 going on Ebay in a few minutes. I had it in the kitchen once upon a time, picking up a line level signal or switched into it's tuner.
Anyway, I just took it out of storage today and fired it into a pair of AC650 Pinnacles and at 10 o'clock volume my ears were close to bleeding and the sound was ..RICH. I have to tell you there build is a lot less than a 330 H-K but they sound as good, maybe better.
 
Oh I forgot to mention, the RX203 has an honest mono switch like the 330H-K as well. I drove one Speakerlab Das2 in the kitchen and one in the garage. I delivered line level stereo to those rooms and a couple more with a Luxman R361....usually inputing six hour tape off a Toshiba DX-900. I still got that wonderful critter. I had a tech go through it 2004 and don't work it real hard anymore. There aren't many worthwhile radio stations that broadcast TO the woods....
 
Thats a Hansome Reciever! Judging by Rotels Discription, It looks like a well designed unit by someone who took SQ seriously, even with their lower powered Recievers back then. Apparently even thier NEW gear is still competive. Intersting your NAD didn't sound that great. The Amp section of My NAD Seperate Pre/Amp Tuner and Amp doesn't sound enough better than my Onkyo AVR to make it worth my while to change cables. I do use it's FM tuner though via it's Tape out jacks. I'm not knocking NAD, that Preamp/Tuner is a fine unit for what is was, an inexpensive (far less than my AVR) Preamp/Tuner with a very good phono stage and FM Tuner.

I think Rotel is often under rated. Many Brands of the mid-70's on had their share of sleeper reciever's in terms of SQ and Rotel is no different. For someone looking for a good quality vintage reciever Rotel should be considered a serious contender. And since the more popular names Like Sansiu, Pioneer and Marantz are begining to demand top dollar, these Rotels, can be real bagains, and like those other Brands, the right unit's can hold their own with the best of them IMO.

AnalogDigit is correct, back then some of the lower end Recievers were built to high quality standards like the higher end ones, only with less power and perhaps features. I have a Realistic STA-7 10 wpc Reciever from the late 70's that sounds way better than it has a right too, even the darn Tuner works great. While the Tuner in my midrange 2001 Onkyo AVR works OK, it's no match to the one in that 10 wpc Realistic from 12 years earlier.

There's one going for £55 near me. Not sure if anyone is still alive on this thread but be cool to get a conversation going again
 
^ Actually the original poster has in fact passed away and a lot of the other posters haven't posted in years.

Not sure what conversation you want to get going but I would suggest creating a new thread.
