    Troubleshooting Pioneer VSX-1016TXV (only left channel works)

    I have a Pioneer VSX-1016TXV receiver. It’s been a pretty good receiver. However the right speaker channel has stopped working. It seems all the other inputs are not working either as I’ve tried them all with speakers I know are good. The only channel that is working is the left speaker one...

    Marantz 140 Peak lights on and VU Pinning at power up.

    Hi! I’ve had the same Marantz 140 for my entire life (mom purchased in 1975) and it’s never had issues. Recently, peaking lights started coming on at power up but the amp still played fine. Now peak lights illuminate and VU meters shoot to the right and speakers buzz very loudly. The amp still...

    Stiff slider on cassette deck locks up mechanism.

    On my humble 2-head Mitsubishi DT-12 cassette deck, there's a slider which engages when recording. This isn't like a fader, it's either engaged or not. This slider bypasses cassette audio and plays the Audio In. The issue is that the cassette mechanism needs to pull the slider to record, however...

    Nasty hum in Adcom GFP-555 II preamplifier

    A while back, I got an Adcom GFP-555 II preamplifier. On powering it up initially, I found that signals monitored through the unit's headphone jack sounded just fine. The sound coming from the unit's main output was another matter. It had a nasty 60-cycle hum. Has anyone here who has owned this...

    Accuphase E-202 blown power supply

    I started working on an Accuphase e-202 for a friend, they weren't sure what was wrong with it as it had been sitting for almost a year since it stopped working. I was going to power it up on a dim bulb to see what was wrong with it, but opened up the amp first to see if anything was visibly...

    Using a Luxman L-80V that was recently taken apart and refurbished - caps, transistors, the works. Was running beautifully for a while until I went away for two weeks so it sat without use. When I came back upon powering on it produced a very loud and variable hiss that eventually died down...

    Heathkit W-7a bias voltage fluctuation

    Hello, I have myself a pair of Heathkit W-7a mono blocks. They had been re-capped before I purchased them. I noticed one sounded a bit distorted in the higher frequencies so I changed the tubes and it sounded weaker in higher frequencies than it’s counterpart. I checked the bias of both amps...

    Sansui 6060 Two blown Fuses

    I just opened up this Sansui 6060 receiver that was given to me not working. I see that two fuses F602 and F603 are blown. I think I need to systematically start testing components and connections on that entire circuit board that has the fuses and relay. What do y'all suggest, please?

    A little while back, I picked up an 8-track deck from a thrift store. It's a Probe(?) DX-5000. I can't find any information on the company that made it, let alone any manuals. This is what it looks like: It plays and records fine, and both sound pretty decent for 8-track standards. However, it...

    Clipping/distortion from receiver...definitely internal EQ related

    So I have this aging receiver (TEAC AG-V8060) that has stood the test of time up until recently. I noticed that the left channel sounded like it was clipping. At first I thought I blew a woofer cone, since it was mostly occurring with the kick drum. I freaked out and took the cloth grille off...
