Another burnt Nikko Alpha 230
I have found a coupe of similar threads but the schematic links are dead I am asking for some fresh help here.
Nikko Alpha 230
No idea of its history
powers up as found with 1 fuse missing from its upper fuse bank (see photo 1)
no smells, no sounds
measure across empty fuse holder + 120vdc / 0vac
(yes I blew a fuse first)
measure 4 (front of case) transistors 2sa1169 - continuous
All remaining transistors mtd. to heat sink not open
Is this simply a question of changing over the open transistors, or is it likely a much bigger job.
Are these transistors substitutable?
Oh yes... any schematics floating around out there?
Thanks for any help.
