Good morning,
I bought a used SOY. Great amp, but it has a problem. When i turn it on, sometimes bass is lost. I've to switch it off and on few times to have bass back. Also, sometimes bass disappears when I flick through the era/bright switches. I remade all the solders, and when I resoldered the 50+50UF cap things improved...just for few days.
I plan to change the can cap, but I'm not sure this will solve the problem.
Any ideas and/or suggestions?
Thanks in advance
Massimo
