Just replaced the transformer on a friend's Lasonic TRC-920 (this one worked perfectly: http://www.jameco.com/z/P-8658-Power-Transformer-12V-4A-117VAC-Wire-Leads_221356.html – even has pretty much the same size as the old one).
While the power is restored, the right channel of the box is dead. I suspect it's a damaged LA4440 amp IC but would like to take a look at the schematics before I attempt any more troubleshooting. Does anybody happen to have either a service manual or just the schematics for this box lying around?
Thanks so much!
