I had a gig with my band tonight & one of my main Power Amps went down.
It has protection circuitry to disable the whole amp & to stop further destruction.
I just opened it up & narrowed it down to the Left channel.
I'm now able to get the Amp to turn on by disconnecting the power to the Left ch. outputs.
The Amps are Sankin 2SA1216 & 2SC2922 (4 of each)
I doubt they all blew. This happened before & I had it repaired but there is currently no local techs.
I think I can do it with a little advise. ;D
What is the best way to find the Bad Amps ???
There's no way to turn on the amp with the Left channel connected because the protection circuitry will kick in, so... what to do?
Thanks in advance.
