Wow! How many power tubes can we fit into an uncomplicated amp?

Issue was it was blowing the (8 amp) fuses. One tube is definitely bad (as in broken), and it looks like a mouse made the amp its happy little home.

Presently cleaning it all up, and testing current tubes. They're from all over the place, so will jot down the current draw to try to get matched quads.

One of the equalizer knobs is missing, as is the volume knob, and the treble pot is broken (and also missing a knob).

Hi-ball estimate of current parts are:

Eq knob: $1.35 https://store.mesaboogie.com/products/knob-408550-graphic-eq-slider.html

Dial knob: $9.20 https://store.mesaboogie.com/products/knob-408115-large-numbered-with-set-screw-p-print.html (need 2)

Fuse: $0.58 in stock

Pot, treble: Researching. Looks like a 200 ohm, with push-pull

Tube: $484.30 (all 12) https://www.amplifiedparts.com/sets-by-amplifier/mesa-boogie/bass-400-plus (Electro-Harmonix)

or

Tube: $431.40 (all 12) https://www.tubedepot.com/products/jj-6l6gc-power-vacuum-tube (JJ)

And shipping, can't forget shipping these days.
