I found this amp in the back of antique store sitting on a dusty window sill. It seemed mostly intact, if a bit worse for wear and filthy. I plan on restoring it to a proper little practice amp, because you can never have enough gear.
It is a period of civil war. Rebel spaceships, striking from a hidden base, have won their first victory against the evil Galactic Empire. And I decided today was a good day to break apart the old cabinet and start making a new one.
The speaker cone had some tears in it, including a 1 1/2" long tear along the outside edge which created an audible flapping noise at high output. The others were small punctures, also in the edge of the speaker cone.
Since there appeared to be nothing physically wrong with the amplifier, I plugged it in and turned it on. No blue smoke. I plugged in the speaker and turned it on again. A "vorp" emanated from the speaker, and fiddling with the knobs caused crackles and pops. I grabbed a bass guitar I had gotten at a flea market and plugged it in...
I started by unplugging the speaker and removing the grill cloth, taking pictures of screw placement and bagging the fasteners together in logical groups. The result was easy access to the collected layer of filth. Bleugh.
