Hello all, I’m exploring a possible repair on a Pioneer SA-1490 receiver I got from a friend who insists it was working for him before giving to me. I’d like to save it from the recycle pile but it’s not working now. Two sentences about me. Although trained as a EE, I’ve leaned on more of the...

Hello AK friends! My first post post here besides the intro, so sorry up front for any mistakes. I am going to look at what appears to be a recently serviced Pioneer SX-850 in excellent condition. Seller is asking $700. I've researched here and this appears to be a unit worth having so my...

Hello, I could use the support of everyone here. I have a Rotel RSX – 1067 receiver, which runs a five channel stereo system in my main viewing/living room at my home. There are two powered quad front speakers, two quad passive rear speakers, a polk center speaker, and a separate zone running...

Sometimes you get lucky and the 30 year-old LD player that had been in the attic since 2011 still works. Pioneer CLD-D504 - dual side player. Supports Dolby Digital AC-3 by outputting it over an RF output, but otherwise analog only outputs.

Hi! I found a Pioneer FX-330 (identical to SX-330? except radio bands?) in very good condition in a charity shop. It has a combined Volume / Balance knob, where it's "split" in two, and the inner part is balance while the outer part is volume. Problem with mine is they are completely stuck to...

I'm not sure how this thread will evolve, if it even does evolve. But this is too interesting not to document it. I reconnected with a college friend back in January on some emergency services work he did for me. As a result, we have gotten together a few times since then. At a pub playing...

Hi, Recently bought a Spec-1 that was on a tech's bench used as a switching device (as I understand). This unit appears to have been a donor unit used to keep other units in service as various parts are missing. The unit is operational and rather well. Great!!! But I want to restore it as...

Hi everyone, I'm working on a vintage Pioneer DT-500 Audio Digital Timer and hitting some perplexing display issues. I believe it's an NE model (220V 50Hz, no external voltage/frequency switches). This unit was not used and not connected to electricity for over 20 years before I recently...

I recently inherited a fully functional Pioneer SX-535 receiver (rated 20wpc). Will running this receiver with McIntosh ML-10C speakers cause excessive clipping even if I just listen at low-to-moderate volume in a smaller room? I also have an Onkyo TX-2500 MkII rated at 27wpc but currently...

Hi all, I know it might come down to personal opinion, but bear with me. I just got a pair of Pioneer CS-616 speakers for £165 including shipping. Thing is, they got damaged in transit. They seem to be working fine, apart from one of the tweeter cones being pushed in and coming unglued...

SX-750 that I've had for decades. Partial recap, LED lighting, and stripped/replaced the veneer on the cabinet with cherry. Looks great. First time doing veneer, very pleased with the outcome. Anybody else done the same? I have an SX-550 that's up next.

Hello! I'm new to the forum but have been browsing for some time fixing up my parents old audio systems. I've come up with a fix for something I finally feel is worth mentioning. The old school Pioneer PL-200 turntables from the late 70's/early 80's are evidently notorious for having the spring...

I started a recap job on an SX-650 given to me by my big brother a year ago. It is the version that has IC's in the phono section. The cabinet is in rough shape, but the faceplate is clean and it has all the knobs. This receiver has been worked on before. The power switch had been bypassed...

Hi all, I’m hoping someone can shed some light on this Pioneer SX-9000 I’ve been fighting with: When I first got it, testing showed that the left channel was very low and very distorted so I set about a full cleaning and rebuild. After the total rebuild, the EXACT same problem persists -...

Good morning all, I posted a couple of weeks ago about my CT-F9191 that has been sitting for a while, and is now not operating properly. The basics are this, FF works fine, Rewind does not, Play seems to function properly but I'm not getting any sound. Also, with no tape installed and the...

I’m working on an SX1000TD. I have 3 different service manuals for this receiver. The one for the SX 1000TD -B is the one I assume for this particular unit. The control amp board shows a 10uf 10v electrolytic cap at C601 and 602. My board has a .47uf poly cap here. Same board number...

Hey all, I recently acquired a PL-9, one of my “grail” tables. After fixing the auto mechanism it’s running quite well and I’m considering swapping out the Technics in my main system. I’d like to move the Denon cart over as well but it’s VTA sensitive, and I haven’t been able to find adjustment...

Good evening AK, So, a few years ago I was lucky enough to to pick up a Pioneer CT-F9191 from a guy who just had it sitting in his garage, for $50. I didn't have a clue, at the time, what I had. I took it to my audio tech and had him take a look at it. He replaced the belts and the transport...

I am working on a rebuild of my SX-1000tw. Most parts are straight forward but there is a capacitor on the bottom side that connects to the ground side of the filter capacitor. I have seen pictures of units without it but several with it. I can just order an axial replacement but was just...

Yesterday, I received my new-to-me Pioneer SX-434. The ad on ebay said it was recently serviced and in good working order. The trouble is, I discover after plugging in that the only thing working are the dashboard lights. That makes sense because the transformer secondary that feeds the lamp...

So this amp finally burned up one of the output transistors on the left channel and since it has been repaired at least 5 times in the last 2-3 years by a 3rd party with who knows what quality replacements we decided to just buy the parts ourselves and change all 4 output transistors and all 4...

Hi everyone, I have a vintage Pioneer setup, including the SPEC-1 preamp, SPEC-2 power amp, SG-9800 equalizer, CT-F1000 cassette deck, and RT-707 reel-to-reel. I've noticed static on the front panels, especially when I touch them. I suspect this might be due to improper grounding. (NO HUM OR...

Some time ago I found my old box of casettes, and I have some that I would like to listen to. I have 3 casette decks, and none of them work. One is the yamaha double deck I proudly bought as a kid (1989 ?) , a K-W132 (even have the original box) that doesnt work at all, seem to be a belt...

Hi guys, I have a restored SX-1010 that I have used for about a year since the restoration. It got the works during the restoration, including the brand-new power supply board. It's been working flawlessly until recently when the sound started to fade in and out for no reason. I immediately...
