Question about Wurlitzer Jukebox 1015 One More Time 100-Disc CD Changer
Only front box lights come on. After inspection found fuse si5 blown. also D6 & D7 blown apart. Check caps and bridge(GL1) and they tested good. Bridge puts out about 68vac and 29.5vdc. However i am only getting 9.3vdc to the s&cc. I check volts at D6 & D7, anode side, getting 11.7vac, the at the cathode side and getting 9.2vdc. i'm guessing i have the wrong diodes. Currently have 1N5397 diodes installed. Please let me know if these should work and the problem is somewhere else, or they are wrong and what are the correct ones. any help would be greatly appreciated, by the way when you flip the coin switch the LED-M flashes.

Assuming I am looking at the same diagram for a 'Compact' amp....the circuit you are looking at is unrelated to GL1.
The two diodes rectify 10VAC from the transformer to a rectified +12V DC which supplies the mechanism. To blow both diodes I can only assume that you have a dead short to ground or -Ve somewhere.
Check both diodes and fuse are good with the mechanism plug disconnected. You should get 12vdc at the cathode of the diodes.
I don't know about the diodes you are using but 1N4001 or 1N4002 or 1N4003 should work fine.
The 12VDC comes out on pin 2 and pin 4 of the mechanism plug. Make sure the diodes are the RIGHTway round or you'll end up with MINUS12V.
