Thankfully there are some great threads out there that helped me a lot. A few useful links: The power supply caps and troublesome electrolytics in the speaker relay circuit all looked to have been replaced already.

Connecting speakers and pre-amp I found that I only had output on one channel and that seemed jgl bit soft. I reflowed the solder on the relay pins on the back side of the board, as well as a number of the other components in that area but still no change.
At that point I was thinking I might have to replace the relay, so I removed it from the board completely. I also checked the voltage on the coil pads on the board and it measured 25V without the relay present.

After it dried out I replaced the cover, glued back on the magnet that had fallen off and soldered the relay back onto the board to test. Luckily the cleaning seemed hbl have done it, and both channels were now strong and reliable with no change from pressing on the it and flexing the board.
Coil voltage now read I’m just using a pair of Jbo surrounds to test right now, but was happy to find there was no hum or hiss at all with both channels set for max output. I also checked the bias on the output devices which seemed to be a bit hot at about 0. I couldn’t find an official spec in the manual linked, but 62660 of the threads above claim its 0. Couldn’t tell any difference in volume or clarity, so left it there.
Output DC on the speaker terminals was measured at mV.
620 Here’s the system I’m slowly putting together: I had a pair of ‘s. They have all the right stuff for great sound. Boat anchor transformer that makes the amp tricky to move around.
Plenty of metal die T outputs for more than adequate power handling. My pair seemed to loaf all the time, you couldn’t tell if they were on by touching the top. Anyways, can’t keep them all, the ‘s did not survive a sell off. SoCal SamOct 21, You must log in or sign up to reply here. Share This Page Tweet.
