    Problem with Pioneer SA8800

    Hello and welcome. I apologize in advance for my broken English, but it is not my native language. Pioneer SA8800 came to my table and was supposed to have a "slight defect" As I had already made such an amplifier before, I started to perform a basic check of the fuses and measurements to see if...

    Pioneer SX-440 wonky power supply and distortion

    Hey team I'm working on my friend's Pioneer SX-440 and trying to work out why I'm getting low voltages. You can see in the attached doc I'm down on volts especially on pin 2 that should be 42v. Not sure why. I've tested the transistors on this board and are OK. I checked the diodes too and seem...

    The dual is €135, Pioneer €110 and the Technics €150. They are all working perfectly and in good condition. Which one out of these is the superior option?

    Technics SL-B2 vs Pioneer PL-112D

    I am planning to hook an AT-VM95E cartridge on one of them. Both of them are belt-drive, I've tried looking online but can't really figure out which one is higher quality. The Technics SL-B2 is €50 and the Pioneer PL-12D is €100. I currently have a Dual 616Q that malfunctioned. Would these be...

    SX 850 Relay Clicks On then Off

    Hi I put a new Power Supply board in my unit about a month ago and everything has been great, barring an issue with the left channel being slightly weaker than the right. I did perform a DC offset when I had the cover off and thought I did everything correctly. I had also done a rebuild of the...

    SX-1250 Tuner board.. oops

    Hi everyone, I revived my very sick SX-1250 using the rebuild kit sold by Peace Love and Music. This is a kit for ALL electrolytic caps, and quite a few transistors and diodes. Good news... The Amp is fine. Both channels sound equal and clear. The phono board is fine...

    Pioneer SX770 left channel preamp out hiss

    My SX770 has a hissing noise only heard on the preamp RCA out on the left channel. It is the same volume regardless of how loud the volume is turned, and is present regardless of which input is selected. Any idea which transistor may be the culprit? Everything else works perfectly.

    Hello everyone, Let me introduce the problem a bit. Last summer I bought SX-580 at a kinda garage sale. It was waiting for it's turn to be fixed (I repair things as a hobby) and so now is the time. Initially it didn't start, there was no sound, one channel was getting high (on the meter). After...

    Sx-990 burning emitter resistors

    Working on a pioneer sx-990 that keeps blowing the amp fuse on one side. While checking everything out I replaced the fuse again and the 2 watt emitter resistors started heating up. Then I realized I put a 5 amp fuse instead of the 2 amp it calls for. So I turned it off right away but I would...

    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.

    Picked up a (near) mint Pioneer RT-707!

    I'm now the proud owner of a Pioneer RT-707! Spent about an hour going over the machine before making an offer - heads were so gunked up I literally thought they were corroded, which would have been a shame since those alloy heads are hard to come by. I don't think the machine had ever been...

    Pioneer SX 1010 - Issue with Phono (Equalizer) board

    Good day. I've been working on a Pioneer SX-1010 that has issues with its Phono board. It gives out constant cracking noise, sometimes very loud, getting the amplifier into Protection Mode. This issue is only in the Phono stage. All other inputs work fine. With some investigation I found the...

    Pioneer SX950 DC Offset Adjustment

    When setting DC Offset are the 5.1k resistors really necessary? I’ve read on audiokarma that they are not. Never seen this before.

    Pioneer SX950

    I need to remove the faceplate on a Pioneer SX950 and can’t turn the set screw on the radio tuning knob (the large knob). It looks like an Allen wrench set screw but I can’t tell. Doesn’t seem like it would get chewed up from a lot of use, but that may be the case. I may need to drill it out. I...

    Pioneer PL-6U not working

    I recently bought a Pioneer PL-6U that came with the original box and when I tried to turn it on, the motor does not spin. The motor spins freely by hand, but does nothing when the switch is changed from off to any of the speeds.

I have a restored 1010 that’s my daily driver, and the thought was to restore the 1250 when something happened. Well, something finally happened. Last night I was listening to a record, and I...

    So I purchased a set of Pioneer Elite TZ-9 LTD from a member on here recently. I had them delivered through UShip and when they arrived, one of the ceramic graphite mid range domes had a hole in it. Once I got the mesh cover off, it was cracked much worse than it looks and is destroyed. I put an...
