realistic

I been trying to get this realistic 820, belongs to a friend. Very dead on arrival, one fuse dim bulb glowing. Outputs were bad, a cooked transistor for good measure the filter caps were replaced. My limited experience, has me going around in circles. If I hook up a speaker to either A Or B...

Hi everyone! I'm in the process of setting up my first audio system, and I'm currently on the lookout for a good amplifier. I've narrowed down my options to three choices available in the second-hand market. Through my research on this forum and other websites, the Kenwood KA 4002a stands out as...

In case anyone was wondering appearance wise the difference between the Lab 420, 440, and 500 turntables. Bottom left is the 420, right is the 440 and top is the 500. Personally I think the 420 has better quality than the 440. The 500 I’ll never part with it’s just such an all around great tt...

Hey, y’all! I’m new to AK and very new to analog equipment in general, so my apologies in advance if this isn’t the right place for this or if this is a silly question. Not sure if calibration is the right term for this either. I recently purchased a Realistic STA-120B receiver. I’ve really...

Guys I finally got some parts to get going on the 820. Had no sound, you could clearly see, some cooked resistors and awful looking transistor. So I replaced the bad components. Power it up on the DBt, and the resistor went again. So I got a couple of filter caps, put them in and up in smokes...

Looking at picking up a Lab-8500 TT. Does not appear to be much info out there on them. As far as I can tell it was a Canada (and possibly Euro) custom edition of the Lab-500. Research points to it being built by Mitsubishi (possibly ITT). It's a quartz lock direct drive. Has a repeat play...

Good evening AK members, hoping to get some help with a recent thrift store find. Hope this is posted in an appropriate space, apologies if not. Anyways, I recently picked up this Realistic STA-235. It’s fairly nice looking, clean, and was only $50 which in my area (Northeast USA) doesn’t buy...

I just got a realistic STA-100 on the cheap. Cleaned it, but cannot find the problem as to why it works only in the right channel. If I plug my speaker LL and RR in the speaker set 1, only right will play if I select speaker set 1 output. If I select Rev A output, only left speaker will play...

Hello, AudioKarma posters! I am looking to replace some of my stereo equipment because something in the chain is not working correctly, I currently have a Realistic LAB-2100 turntable, running into a Realistic STA-2290 stereo receiver, into Sansui SP-1200 speakers. The first couple of times I...

I have a pair of Mach Two 40-4032. The caps values and measurements are; 1) 33uf - 37.78, 2) 2.2uf - 2.4, 3) 2.2uf - 2.4, 4) 4.7uf - 5.5, 5) 4.7uf - 5.5, 6) 8uf - 10. What are the tolerance for the caps? Thanks everyone again for your help.

Hi All, I picked up a Lab 290 not too long ago and the previous owner bypassed the speed selector switch with what he assumed was a power switch? I rewired the switch to the solder points he had previously used but obviously its just an on off for 33rpm from what he did. There are a few other...

Hello everyone, This week, I bought a Realistic MTA-15 table radio off the Goodwill site because it was cheap and I wanted a nice radio that might sound good and didn't have DSP, just for a change of pace. Like some things you buy at a thrift store, it can be a hit or miss proposition. No...

Hello everyone! I have a Realistic Lab-270 turntable. I’m setting it up in a new house and noticed the speed sounded slow. The RPM Wow app showed the speed as 32.57. I played my guitar along with Dokken’s “unchain the night,” and it was perfectly in key as Eb. But the song is the key of E. I...

Hey all! Newbie to the forum here... just figured this would be a good place to ask this. I'm renting the second floor from my boss (we do drywall from hanging to finishing to painting), and am putting together a living room in the second bedroom. My boss had an old Realistic AV-900 receiver...

I have a sta2100, lab420, mach two and tr802, all was working perfect until I plugged in the 8track into unswitched outlet on the 2100. I saw white smoke come from amp, now no sound from either A or B speakers. All lights and meters are working, just no sound. I'm not a repair guy, but is...

I've been looking with no luck to find used OEM to replace the tweeters on a pair of Realistic Optimus 50 speakers. I'm wondering about the experience of others when replacing the 0766 tweeter with some other used but non-OEM tweeter. Any experience using a modern tweeter? The 0766 tweeter's...

Looks like il be adding to the fun as I am as well a STA78 owner that has crackling/popping out of only the left channel. After searching the forums, I put together that this is likely a bad transistor and decided to start doing a cold test of the transistors using super cold spray. During...

Some classic speakers are fabulously documented while many are shrouded in mystery. Which must frustrate hobbyists, judging by frequency these forums are peppered with unanswered requests seeking crossover data. Feeding my own curiosity about vintage Optimus and Nova products has unearthed...

I have a Realistic STA-18 receiver I was given by a friend that I'd like to repair. The transistors in the amp board are T1S92's, T1S93's, and T1S97's. Would it be a bad idea to replace these with KSA1845's, KSA992's, and KSA1845's respectively? Are the any better modern replacements for these...

Hello all, I am servicing a Realistic STA-225 and am pretty sure I popped these two connections loose. I replaced two capacitors on the tuner board, and had to move the schmidt trigger board out of the way. I made a rookie mistake and did not take pictures before I started. Pictures included of...

Long story short when my right side speaker went out I immediately thought it was the receiver. So for the last month have been shopping and purchasing vintage receivers, however after everything said and done it was actually the speaker that went out. It seems like I'm only getting the Tweeter...

Good news! I stumbled upon a Realistic STA78 at the local GoodWill and nabbed it for a steal. About a week later found some Marantz Imperial 6s at the same exact place. Figured this could possibly make a great little system. Now for the bad...It has loud static out of the left channel. Before...

I got a pair of used JBL 216 bookshelf speakers that looked to be in really good shape. One woofer wasn't working when I first connected everything, so I pulled it apart to measure the coil's resistance. When I pulled the woofer out I saw that it was made by Realistic. I didn't expect to see...

Hi, long time viewer, first time member. Ive seen a lot of threads on the Realistic 7B but still left with questions. I scored a Nova 7B from a guy who bought them, according to him, in 78' when he worked at RadioShack. He claimed to have used them very few times and then retired them somewhere...
