This is hard to explain, I'll try to make a video later when I have time.

SOMETIMES when switching channels on my Hot Rod Deluxe, my amp sends like a double signal. I end up on the channel selected but it delays a split second because it is sending a double signal. It should do this:

Press button (old channel) -> change to new channel

Instead it does:


Press button (old channel) -> new channel -> back to old channel -> back to new channel


^ this happens all in a split second, and you can see the LED blink really quick.

I know it is not the foot switch because I have 3 foot switches and they all do the same thing. I bought a brand new foot switch just to test this, I am convinced it is the amp. I have had this amp for a long time but it just started doing this in the last 6 months. This only happens 1 out of every 5 or 6 times I go to switch channels. It does NOT happen every time.

anyone have any idea?

Common problem usually traceable to R78/R79 in the +/-16VDC power supply. They overheat and develop bad solder joints.
