And I think it just killed my power amp tubes. I was playing with it, and set it to max and tried to push the volume to see if my amp would start clipping. The volume on the master was at around 6, and it had this sweet tone that was right at the limit, so I stomp on my distortion pedal, and tube screamer, and about 5 seconds later I hear the amp just fade into nothing. I panic, and flip the standby switch, and turn the attenuator to 0. Turned off the amp and waited about 10 minutes. Then went through the sequence of warming up the tubes, guitar volume in zero, I then flip the standby to on, and gradually raise the volume on my guitar. With the master at 6, I expected quite the loud sound this amp makes at that volume. I usually can’t go past 3 without having an angry wife knocking on my door. But this time, the amp sounded as if the attenuator was still active. I look to make sure it’s on zero, and it is. I then remove it and connect the speaker to the amp, and still low volume. The amp still has good tone, but I lost a good 30% or so of overall volume.
The tubes light up nice and orange, the pre amp tubes are harder to see, so I’ll remove some covers tomorrow and have a closer look and give them some love taps. This is a Mesa Subway Rocket, and the tubes say Mesa so, it’s possible they’re the factory tubes from the 90’s. Should I replace just the power tubes since the volume loss is in all channels? Or could I be looking at something more serious?
Here’s the attenuator I used. I looked it up, and it’s supposed to be a good one. It was quite cheap at GC used gear pile so couldn’t pass it up.
