    Vintage Denon amp output on 0 volume?

    Alright so apologies if this is not the correct place to post this as I'm yet to get my head around this site... I got my hands on a Denon PMA-320 integrated amp (circa 1989) today and have spent a couple of hours troubleshooting an unusual output issue: when the volume is at 0 there is still...

    Marantz 3250b left channel cutting out

    I have a rack consisting of a marantz 3250b and 300dc, and the left channel cuts out. It goes silent while the right continues to play music, until I turn off the speakers, max out the volume until the vu meter starts showing something, lower it again, and turn the speakers back on. Doing this...

    RX-495 Issue

    Hello Everyone, I purchased my RX-495 back in 1997. It has been flawless until 2024 when it would suddenly "click" and turn off, either at low or high volume. It is sensitive to vibration. Something as little as putting my coffee cup on the desk can trigger it to turn off. Sometimes the...

    1070 Restoration

    It's been a while since I worked on a Marantz. Just fished this mid-1970s Marantz 1070. I own a 1060 and it's been restored as well. The 1060 is warmer, more tube-like. The 1070 is very clinical, very clear and such a wide dynamic range. The highs are very high and bass very low. Replaced the...

    Project: Solid State Relay (drop-in) replacement for speaker protection

    Hey guys, I have been working on a quick project: A (drop-in) solid state relay replacement for relays with the footprint of Omron's MY2 (and similar) used as speaker protection relays. Today I'm too lazy to write a long post, so Q&A it is: Why? Because I don't think I have seen a compact...

    I’ve been restoring a NAD 214 power amp with my 9 yo son for a fun learning project. He’s been doing great with soldering and staying interested. Initial symptoms were: unit powers on, soft clipping light stays on, no relay click. Front lights stayed on even after unplugging the unit suggesting...

    Schottky 12v rectifier

    Hello! I'm working on a preamp (in name only), by which I mean a bunch of relays on a switch. The power supply I have for it is a 7.5VAC (1VA) transformer. With no load, it's at something like 9.4VAC. My relays are 12v relays, drawing something like 11mA. My regulator (a 12vdc-12vdc DC-DC...

    I have a NAD 2700 and I heard the output relays go in these? I cleaned the pots with Deoxit but at lower volume it occasionally has a bit of static. Loud appears fine and no scratch when turning knobs. Could this be bad relays? Would these work...

    Model 22 New Relay not responding

    Replaced the relay in my Model 22 cause I figured the old one was bad. Same problem, relay not clicking on. What do I need to look at next? This amp is all original so should I be planning on recapping the power section?

    Pioneer SX-880 Recently Moved, Now Relay Click Is Intermittent

    Hi. Sorry for another Pioneer protection-mode thread. I feel like this one could be fairly easily solved. It always worked fine up until I moved into a new house last week. It was packed well and went in a moving truck. It worked the day I set it up in the new house. Today, there was no relay...

    So I picked up a Yamaha CR1020 - no relay click

    This thing is beastly! And gorgeous. Seller says that last he checked a few weeks ago it was fully functional (and I believe him). He bought off reverb around 2019 so hasn't been serviced at least since then. Has been serviced at some point because the VU meter lights are green (yuck) and the...

    Accuphase P-266: replacing the NTC to limit the inrush current

    Hi everyone! I completely recapped the Accuphase P-266. Once the amplifier is on, it runs great! But charging 4x 22,000uF filter capacitors causes a high inrush current. Every time I first start it, the circuit breaker is trips because the inrush current is too high. This also happened before...

Just learned to switch speakers to OFF before turning the unit off. Last week I noticed right channel...

    Nikko NA 550 Amp Works Well But Won't Go Out Of Protection

The center point DC output voltage is a good low 10mv from either channel, so that isn't an issue. I reset the bias so it is running nice and cool. To put it...
