    Hi, I am in the process of setting up a second audio system for my bench area and was wondering what you guys would go for of what is presently available on ebay. Or if anyone has something for sale, I'll certainly would take a look at it as well.

    For the fun of it (and a bit of nostalgia) I wanted to get a receiver from the mid to late 70s, but would certainly appreciate any other suggestions. I'm planning on pairing the receiver with a pair of freshly refoamed JBL Control 1s, and still need to get a CD player as well.

    Most important for me would be the serviceability of the receiver, because even though will try to get one that looks to be as good as possible (within a reasonable -non- "vintage" item price) I am sure it will need going over, so easy access to schematics or even better to service manuals would be a must. Another factor would be no exotic unobtanium parts, as I don't want having to hack something just to get it -maybe- working, or even worse end up with a model that cannot be repaired at all because due to limited availability the needed part might cost more than the receiver itself.

    As a first choice, I was of course looking at the SX series which was very emblematic of the era and had lots of good looks and the performance to go with it.

    BTW I was also considering the other main brands of the same era (not sure it will be polite to mention them here) but we all know which ones they are.

    So if you where in my situation, what would you guys go with?

    Thanks in advance.

    I have a SX-850 and it's a nice amp. Recapped it several years ago (not too difficult) and was using it in the garage set up, driving a pair of recapped Norman model 8's. A few months ago I came across a SX-1010, at a good price. Put it in place of the 850 and was blown away at the improvement in SQ.

    I also have a Sansui AU-919 in my office, driving a pair of Ascend Acoustics Sierra 2's. I had always planned to, at some point, bring the 1010 into the office to see what it sounded like with better speakers. Friday, I sat down at my desk, turned on the Sansui and...................................nothing. So, I was "forced" to bring in the 1010. Don't know if it will stay once the 919 is repaired, but so far I'm liking it. Considering that the Sansui is recapped and the Pioneer is not, that's saying something!

    The one issue with the 1010 is, as one member here described it, it's an easy bake oven and tends to "cook" the power supply PCB so that's something to look at before buying (if you can). Even so, it shouldn't be that difficult to rebuild that board (caps and resistors). Fortunately, mine didn't get much use and shows no signs of overheating. And, I've got a small, computer type, fan blowing into it to prevent it.

    The 1010 was the first 100w receiver and pioneer came out with the 1050 and 1080 (both 120w) in the following years. Don't know if they have the same power supply issues, but it would be worth checking out.

    Just checked ebay and the 1010's are going for (asking anyhow) less than what the 1050's are. I think one reason for that is that the 1010 is not as "pretty" as the later models. They also have a few push button switches that some people don't care for. (Deoxit took care of the issues mine had.)

    If it were me and I had to choose between a 850 (or 950) that was fully recapped, or a 1010 that was fully functional but not recapped, I'd get the 1010. The SQ is THAT much better!

    Thank for the input. I've been roaming around ebay and doing a bit of research as well on the technical side. I was initially kind of inclined towards the SX-650, even tough it always nice to go for the higher models with a bit more bells and whistles and added power. But prices really start going up fast as one moves up on the models, and figuring I really don't need that much power to drive the Control 1, I still though a SX-650 would be a good compromise. But turns out that series uses a Sanken hybrid in the power output stage that seems its not easy to find if it came to needing a replacement for a faulty one. So I have now shifted looking at the previous SX lineup (SX-535, 635, 735...) which I think came out until 74-75, and which uses discrete TO-3 output transistors that are still available and relatively easy to find. So I am starting to incline towards a SX-737 or SX-838 which seem still to be available at a decent price. It was also very easy to find a PDF of the service manual for this series, as it is apparently for most other 70s Pioneer models. The models above the SX-737 mostly seem way too expensive as the sellers are really pushing the vintage factor to squeeze out extra dollars, but will keep an eye for a decently prices SX-838. Another thing I noticed is the crazy shipping rates that seem now to be the norm, I guess since USPS increased their rates some time ago, everyone else did as well. When was it that paying upwards of $60-75 or even more for domestic ground shipping is "normal". Sounds out of wack to me paying $200 for the receiver and then on top having to pay $60-$70 "economy" shipping. But what can you do, it is what it is.

    BTW, I can still clearly recall when those top Sansui models AU-717 and 919 series came out, they really looked tough and where very heavy, aahh and the smooth feel of the volume control. I would consider them if I where looking for an integrated amp, then who knows maybe I'll take another look at those as well. What happened to your AU-919? I used to think of them as indestructible, but then I never owned one.

    Anyway, I am still not set firmly on any receiver model, will keep looking a bit more. Even took a peek at Marantz, but they seem way over the top price wise, even the lower models. Not to mention Sansui G series. Yes they are nice, but that vintage market tendency really spoiled prices ever since a few years ago. Thanks again.

    Sounds like you know what you are looking for.

    You're right about the vintage market. Too many people simply buying to flip. Fortunately, I bought mine several years ago when prices were just beginning to climb. There's no way I'd buy a 919 today for what they're going for.

    I think (hope) the Sansui is going to be an easy fix. Got to playing around with it and found that it works with the jump switch on (albeit diminished volume). The last bit of recapping I did I had another issue with a wire that didn't want to stretch. Hopefully, this is the same type of issue with the jump switch. Next weekends project.

    I've read good things about the Onkyo TX-4500 Mk2. Might be another one to research.

    As to the increase in shipping, I've said for years that everything is going up except my income. :(

    Something from the x3x series would definitely sound good, BUT just be aware that everything in that series (Except the 1010) had a vinyl covered wood case rather than Walnut veneer. Only the SX-1010 in that series had a walnut veneer case. If you go one series earlier, both the SX-828 and SX-727 have walnut veneer wood cases. The draw back is they use speaker plugs, but there are many easy ways around that if a unit does not come with them. The sound on the x2x series will be as pleasing as the x3x series, and the 727 in particular is still very reasonably priced. They also have very good tuners.

    Hi Keith,

    Thanks for the information. As per your suggestion I went and looked at some 727 and 828 receivers and they indeed look very nice as well, but at least for the few examples I saw on ebay the asking prices for the ones in decent shape where generally moderately higher than for a newer generation 737. Is there some factor that makes the x2x series more desirable? (aside from the nicer veneer cabinet finish). Some crazy high 828 prices as well (one "works fine" at $749, and two "tested & rebuild" at $999 and $1199). What do these people think they are selling. Also saw what you mentioned about the speaker plugs, kind of a weird design. The (reproduction) plugs are being offered on ebay as well for $29/pair plus shipping, talk about the vintage factor :(

    Hi Vintage,

    I'm not sure there is a lot of logic to some of the prices. However, the 828 came out in 1972 and was TOTL in 1973. It is a high quality piece with "stamped in" lettering on the face (stamped in to the metal), so you don't have an issue with lettering loss. In comparison, the 737 was 4th from the TOTL (1010, 939, 838 were above) in the x3x series. Just an opinion, I think the x50 series has become super desirable, which has push people to look at the earlier Pioneers. I was in the same boat. Had wanted a 1010, but the prices were just too high for me, so I looked at the x2x series. I was able to pick up an 828 on e-bay for $200 reasonably. I have noticed asking prices have climbed since then. If you look at the series previous to the x2x series, that would include the SX-2500, 1500, 990. I have both the 2500 and 990. They are both excellent receivers, reasonably priced, and just as good of sound quality (maybe even better if you like the early warm sound) than the x2x series. The SX-990 is common and generally under $200. I have found both of them to be pretty easy to work on, and mostly avoid the troublesome transistors in the later series. They also take speaker plugs, but an easy substitute is using a spade wire connector:

    51S17+HLUyL._SX425_.jpg

    The flat spade will fit right into the speaker plug slots. Also, be aware the early receivers have the RCA jacks closer together than later models. So, it does require RCA cables that fit that spacing.

    I've enjoyed all of the early Pioneers I've had, so I don't think you can make a bad choice as far as sound quality.

    When comparing prices on Ebay, be sure to look for Sold auctions. Use the advanced search button to find that option. One can list an item at any price. If overpriced the item won't sell but some people see the high asking prices and think that is what their item is worth.
