This is the underside of the second amplifier. Work is progressing, however this one suffered previous catastrophic failures. At some point in the past, the rectifier tube socket had been replaced and extensions soldered on to damaged transformer wiring. Other wires had also been replaced. I too,had to cut back one of the transformer leads as the insulation was cracking. The multisection capacitor had puked it's guts as well. The surfaces inside this amp are coated with a tacky, waxy residue. Denatured alcohol is cutting it well.
