pics , please

Sorry. I just found out it had got to do with the pre-amp. But as the amp was playing the front panel LED lights have switched them self off. Tried switching off the amp & switching on, but the LED do not function. The amp works fine though. Behind the amp there are Fuses named Output & Rail Fuse. Anything to be looked upon here ?

regular re-cap,thorough checking of all solder joints,change of all suspicious parts ......

without pics we can't help in pinpoint any of these

if you aren't able to give us what's needed to help and guide you , then better leave that job to someone experienced

I sure can do that. Do u want me to post the internal pics of the amp??

I bought a new pre amp & the distortion is gone. But one thing remains. There is a Hum in both channels of the power amp regardless of the input being connected or not. Please help..

thank you

all I can do is to repeat what I wrote already - regular re-cap,thorough checking of all solder joints,change of all suspicious parts ........

and - as I can see , there are more than few suspicious resistors , which means that some active parts are suspicious too

so , considering both value and complexity of amp , that's job for someone skilled

that's probably least painful and least expensive way
