I recently purchased a non-working Flextone II XL for $40. So I knew what I was getting into. The amp is in great physical condition. It would turn on and 1 or 2 channel lights would be on, and if you cranked the volume you could hear a slight hiss at the speakers. I took it apart and found a problem. On the power cord board there was a capacitor that had a broken leg. I soldered it back and the amp powered up and worked for one sound only nothing would respond, effects, models, eq, only master volume. Then suddenly it went quiet light on but no sound. It would not power back up and every time I tried, a different light would come on. So after letting it sit awhile, I tried again and It came to life. Effect worked, models worked I was in the clear. Until I touched a channel button. If you just let it sit turned on and working, it will all of a sudden stop blinking and go off line with a different light configuration. So now I am stumped. Any ideas?
Thanks in advance
