Hi all, I am new to the forum and, well, I'm here because I made, let's say, a careless mistake. While swapping out the lamps in my JVC SR-201 receiver before having my tea in the morning, I put the wires down for a moment (doh!), and before I knew it, shorted the circuit between the two lamp connectors (pins 911 and 914 on the circuit diagram, square E2). I got some smoke and a burnt out resistor (R805 on the amplification board) and a fuse for my troubles. After replacing the fuse, the amp now will not put any signal out, and it generates a significant amount of heat and smoke if I try to run it even without a load attached, again from that resistor R805, which I've also since replaced. I have tested the transistors on the main board less-than-systematically, and I haven't found any of them to give zero or infinite readings on the ohmmeter.
My question is whether anyone has any useful suggestions from here as to what I might have fried with my carelessness - the service manual is here if it's any help, with the circuit diagram on pp 31-32. I'd appreciate any help, as I am about at the point where I'll just get rid of the thing if I can't fix it.
Thanks for any help you can provide in advance!
