    Marantz 2325 PU01 Multipath and Speaker Relay Short

    Hi Guys, My 2325 lost the right channel while playing music. Pushing the hi and low mutlipath buttons brought back the right channel temporaily. I decided to DeOxit the switches and pulled out PU01. The right channel output retuned and reinstalled PU01. The right channel again stopped working...

    Nikko Alpha 450 replacement relay

    Hello All!! I'm currently working on a Nikko Alpha 450 power amp. It has a dead speaker switch relay, I know it's bad because I've switched it for its partner (speaker A B situation) and the other works fine. The coil seems dead. It's a Takamisawa MAT 2B-119H. I'm having a little trouble...

    Hello folks, I have a Marantz 2270 that I bought from ebay. When I first got it and connected everything, plugged it in the the power socket, it sounded great and everything worked.

    I have a noisy relay that I think needs to be replaced. Marked "Sanu UPM-22012". It a reed relay. I am not sure what the voltage is on this. Perhaps someone know about these. This is in a Rotel RX-1603 and switches the head phones in and out. A direct drop in replacement would be nice but I...

    Sansui 790 low/no left output

    Recently started working on a Sansui 790, audio on left was low. Bias checked ok at this time. I read a forum here on the Sansui 7070 (similar model), and checked for breaks in the solder joints and the traces, resoldered just to be safe, no change. Pulled and cleaned the relay, no change...

    Another channel drop out question, headphones fine

    My SX-838 has had a problem recently where the right channel drops out and/or sounds static-y or buzzy, out if the volume is relatively low. If I increase the volume the channel will come back. Last year the effect was present in both speaker and headphones. Using Deoxit on the volume and...

    G-8000 Pop when relay closes

    Trying to figure this one out, when my protection relay closes, especially if the unit was turned off, left for a minute or so, and then turned on I get a pop of DC out of both my left and right speakers. Measuring the DC shows roughly 100-200mv when the relay closes, quickly dropping to 0. If I...

    Odd Relay behavior in recapped KA-7100 - Please Help!

    Here's a puzzle - I just finished recapping a KA-7100, and the relay acts kind of backwards than expected. DBT test was quickly dimmed, offset and bias set easily, LED may be suspect, although replacing LED also created a weird response. I know LED is involved in normal operation of relay and...

    Relay 981-2A-24DS in Yamaha R-S500

    The relay has the usual issues - kicks in if vol is increased, one side is weaker than the other and sound is somewhat distorted on the weaker side. I tried to wiggle the cover loose in circuit as I've done with other older amps but after trying for a couple of days, decided to desolder it...

    Sansui AU717 dropping left channel after rebuild

    Hi All, I restored my all original Au717 last year following Leestereo's guide and parts list. Before doing this, the channel would drop and would only come back on if I quickly turned the volume knob higher. I thought cleaning all the switches and pots along with the rebuild would have fixed...
