Hi all,
I have two JBL S120PII subs in for repair... Both pretty much output very
low amplified sound. Looks like preamp problem. I will have service manual
and schematics in a couple of days... I can't really locate problem without
schematic, changed three out of 5 surface-mounted amplifier ICs in preamp -
same problem... Power amp seems fully working.
Does anyone know about any common problems with these amps/subs?
Thank you!
