Customer brings in this Falcon combo, it needs ordinary repairs, retube, 3-wire power cord. ANd coincidentally no reverb. And coincidentally the wiper and ground end lugs on the reverb pot were leaning together and shorting out the reverb signal. Two repairs in a row with shorted reverb return signal.
Want to pull the chassis for maintenance, and the trem is not working, so...
Pulled the screws, the thing slides out... half way. it is on side rails like many amps. Can't slide out the front, transformers and stuff hang down, and there is the cabinet and baffle board blocking. SLides back most of the way, but the top of the front panel won't clear the cab frame across the top along the underside of the roof. The side rails extend front to back all the way. everything is stapled and glued. Chassis is piece of sheet metal, flat bottom resting on the rails, then at the front, it bends up to form the panel, leaning back a little angle. Can't go out the front, to get out the rear, I'd have to bend down the panel top like an inch or so. It doesn't want to flex that hard, too stiff, and might not recover its angle if it did. I tried pulling the thing back until the panel top hit the beam, then I wanted to pull the bottom out and rotate so to speak, with the top edge as the pivot point. No dice, no room for the needed radius.
I feel like an idiot, but I am stumped as to how this thing comes out, or for that matter how it went in. I can't imagine they built the cab around it. Looking at the tolex and stuff, it doesn't appear the cab has been altered ever.
I have to be missing something cosmicly simple.

Seriously, maybe they got bent because the way that the chassis comes out involves smacking that pot off something. That could be a clue.
