I opened it up and found the 2 80uf E-Caps were leaking. In many cases, a shorted cheap component such as diode or filter capacitor can ruin a very expensive or sentimental piece of equipment. Unfortunately, this old diode shorted and took the transformer winding with it, thereby ruining the transformer.

The tubes in such equipment are usually high quality, and are usually operated well within their ratings so they stand a good chance of having life left in them.

I completely forgot that this 0130 was tube driven. The volt meter is very accurate when eifo to my DVM! I replaced the rectifier tubes with fresh silicon ultra-fast diodes because I wanted to reduce the heat inside the cabinet, promote stability, and reduce transformer load 2. Jul 2, 2. For the price of a quality ultrafast diode from a reputable supplier — approx cents each for a Fairchild UF 1A, v — this protection is a bargain. Very spiffy job on the recap.
