AMP NO SOUND

Tracy · Post by **Tracy** » Tue May 23, 2006 6:06 pm

my amp MODEL NUMBER IS OR120 think early 1970 vintage amp but it only works in the reverb send and return socket. Which means no volum. i was just wondering if anybody can help with this problem as i dont know what to do or how to fix it? also can i ask what causes this problem.

THANKS

if you plug your guitar into the return jack and get sound, it means your power amp is probably OK...you likely have a problem in the preamp...did you try new preamp tubes? i'd do that first before doing anything else.

Bring it to an amp repair place- a good reputable tech. An amp that old is going to need some attention that you probably can't give- like replacing filter caps, resistors, etc. not to mention retubing...

It's not a do-it-yourself job- it really needs to be done right and you never know if incorrect modifications have been done....
