I just picked up a couple of jukeboxes last night. This one is a Rowe AMI CD-100E. One channel was dead. I had a look and saw both fuses blown on the left channel driver board. I'm assuming this is due to faulty transistors. They look to be original ST-2N6284 & ST-2N6287.
There is a circuit board between the transistors with three diodes and two are open, the one on the left and bottom. Anyone have an idea what the spec is on these diodes?
I will check the driver boards after I get this back together.
According to the back of the PC board below, just the ones on the left (1N4157 AP) and the right are directional. I am assuming that the one on the bottom is then bidirectional. Regardless the one on the left, 1N4157 AP is open both ways so a replacement is needed here.
