Hello AK friends.
One of my buddies recently picked up a CR-620 which turns on normally, however, we get no relay click and no sound. We swapped the bulbs too since we figured why not.
Following merrylanders advice, we tried swapping the 2SD234 transistor out for a 2SD476 (if I recall correctly), which did help some (the 234 was definitely dead after testing it). However, after the swap, we still get no output. I went ahead, in my frustration, and tested the DC voltage at the two large coils as per another user's advice, and no we're getting a 16V DC reading on one coil (the one closer to the transformer), I assume this 16V DC isn't supposed to be here, and the expected (less than 4mV DC) on the other coil.
At this point, we're both frustrated and looking for any advice that may help, we'd both like to get this working as its a fairly cool amp (and my friend doesn't want to be out his money).
Thanks in Advance!
