With or without an instrument plugged into my Hot Rod Deville 410 Combo I get a scratchy noise that increases as I turn up the volume on the amp. Please help. Thanks.

Hi rpride3,

You may have a noisy preamp tube, or possibly solder joint problems around the tube socket connections. You can try substituting a known good 12AX7 or similar tube in each position, one at a time to see if the noise goes away, try V1 first. Do you still have warranty? The tubes are covered for a short time, the amp 5 years. :idea:

I'll buy and trying swapping out the tubes. I bought this amp used from a shop in Omaha. I appreciate the suggestion.
