Vince, on this schematic: http://arcarc.xmission.com/PDF_Jukebox/Wurlitzer/Schematics/544a.pdf The pins to be jumpered are marked with dotted lines. They are: 1 & 2 3 & 8. There is no point in replacing the power diodes unless B+ appears weak or absent. You may find the large electrolytic c...

Thanks for that....will have another look.....

Thanks Ron....but I don't see it. Doesn't mean it isn't there, of course, just that I can't see the forest for the trees perhaps.

It seems to me that if the schematic is in your posession, it would clearly show the amp connector socket/plug, along with the numbered pins - so tracing out the circuit is then easy - and then a suitable jig could be fashioned to bench test the amp. This of course requires the ability to read sche...

Hello. New to this forum and jukeboxes in general. I own a recently acquired Wurlitzer 2710 with the 544 amplifier. I have removed the amplifier chassis intent on replacing old electrolytics, old diodes and molded capacitors etc. as the unit was functioning fine but it seems appropriate to do so, as...
