    Understood, but this is important. Regardless of what you had on hand, THIS WAS THE WRONG THING TO DO.

    I have never had an experience with a modeling amp in a band situation that I didn't hate. I just can't stand them, period.

    Fuse was blown when I got it. I don't know how that can happen, a blown fuse and an open PT primary. It also had a burnt open 1 watt screen resistor, so maybe a tube shorted, taking out the resistor,...

    I just watched a video of a DL4 switch replacement, and they do look very similar, except those are thru board. Also, don't know if they are momentary or not.

    Turns out the hum was also a symptom of running on only one tube. It dropped to a reasonable noise floor once the screen resistor was replaced. So in this case, it would seem the 73 year old customer...
