Analog Audio Repair

I recently serviced a pair of Fender Re-Issue tube amps from the 1990’s.  One was a Deluxe Reverb with a shorted output tube, the other a Vibrolux with a blown cap (literally).  These ’90s re-issues are much like their predecessors, but with printed circuit boards which make it a bit more of a pain to work on them.  At least the Deluxe has connectors for the front panel controls rather than soldered wires like the Vibroverb!  It had some 2 watt resistors that were so charred they almost burned through the PCB.  I had to scrape away as much carbon as possible and seal the board with epoxy before replacing the resistors and power tube.  The Vibrolux had a capacitor which actually burst and both amps had very weak Chinese made 12AT7s.  While I was in the Deluxe I added the de-clicking cap to the vibrato circuit.
