service manual for Marsh A 400 S power amp
In a fit of cleaning I shorted the input to my Marsh A 400 S power amp. The right channel is now dead. No hum, no buzz....and no music. I can't see any melted components. If anyone who has a service manual or knows where I can obtain one would contact me, I would greatly appreciate it. NQ,Dennis.
