Question about Adcom GFA-7500 5-Channel Amplifier
The red light on the front of the amp that is for the left channel surround (rear) is lit and i'm recieving no signal to the speaker. double checked connections, but still no sound from the speaker. all other channels working properly
I don't have experience with the 7500 but I had a 7000 with multiple bad channels (red light lit). The problem was bad filter capacitors on the amplifier boards. The large black filter caps (two per channel) were leaking on every amp board. Its a relatively easy repair if you can solder.
FYI you'll probably need a set of small hex head drivers to open the unit.
