Re: One (right) preamp blow! I've located the problem to...
Hi...
transistors are not ok on the C160 module.
replace all the power transistors and emitter resistors for that channel.
www.bdent.com
and
www.ceitron.com are good for transistors
then here are additional things to check:

same withe driver transistors
Well, thank you petraman7! I was working on it while you posted, The Amp is up and running by now. It turned out only "upper" output transistor was blown. It really had me puzzled for a while as the diode characteristics of that transistor was identical to that of the healthy channel. I changed all transistors by the way just to be sure and a single electrolyte capacitor as well.
Hi Petraman7 Actually your input arrived to me 1 hour "post festum".
Your solution was the right one though. So the helpful rating is there for everyone ...else!
Hi Palaboy7
The "C160 module" is just the name for the an input stage in the preamp section - not too much heat generated here I think. (Got schematics from hifiengine.com)
