Trying to source proper transistors for the driver and tone amplifier board for a Marantz 18.
I've checked schematics and service manuals only to find proprietary Marantz part #'s (Grrr...)
I even looked for an annotated schematic where someone perhaps wrote in some actual manufacturer numbers to no avail.
I'm trying to figure out what modern equivalents I can use. I'm willing to cross-reference from old manufacturer part numbers if need be, but these 34-10XX numbers are basically useless.
I'm trying to find replacements /equivalents for:
34-1004
34-1005
34-1007
34-1008
34-1010
and 34-1011 (or 34-1031 as noted in the service manual
Can anyone point me in a direction? If you don't want share the numbers publicly, I understand. A PM with whatever help you're willing to provide would be fantastic.
I really don't want to dig into this receiver without having some sort of replacement transistors in hand. It has a channel balance issue that cleaning and caps didn't fix (it isn't the volume control).
Many thanks!
