[adrianc]

hi guys this is my first post please could someone help.i live in the united kingdom, and have just bought supposidely a working adcom GFA 555 11, however when it is powered up there is no output from the left channel. i have checked the fuses and one is not working on the left side but does not appear to be blown,(checked with ohm meter) i have changed the fuse and i am getting a very low distorted sound from the amp.Also the yellow light is on on the front of the amp for the left channel.
would anyone have an idea of where i should lok for the fault please??

i have looked on the net ebay as well for a service manual, however i have not been able to find one. would someone have one they could email me please.

Last time I encountered the yellow distortion light, I was working on the input board and the 470uf caps were bad. I can't send you a service manual at this time because I new to the board but you may email Service@adcom.com for a free PDF version.
