Fender Twin Reverb with crackling noise on the Reverb

[Leo_Gnardo]

I haven't yet landed on a use for the long tank chassis.....I think that's mostly why I haven't tossed them out, since there's enough volume and real estate inside to build something into them.....what, don't know. Free metal work, even though cheap. If I tossed them, that's when I'd find a use for them.

Same thought process here. I have used a long tank box to build a dual triode gain & audition test set. And I can see using more for prototyping preamp circuits. Yes the day after I heave 'em all out, that's the day I'll come up with some terrific idea how to use them. And that goes for short tank boxes too.
