I have just recently got my hands on an 80s solid state amp. I love the tone of the amp, but it has a hum. I found an amp guy (who tends to stick with valve amps) who changed the filter caps for me, but no joy. I found that plugging in a pair of headphones into the FX loop Send or the Line out resulted in the hum going down, but I need to use the boost, and max out the volume to get to sensible volumes. I've got its schematic, and checked the connections going to earth and cleaned them with some contact cleaner but no joy.
In summary, looking for somewhere to start to start trying to work out what's going on with it - I'm handy with a soldering iron, but have no idea how to troubleshoot an amp.
