any tube hifi audiophools here?
#2

I guess I fit that category, however I use new components when I build something. I've been building a 300B amp since last winter, though I got sidetracked with rebuilding a Philco 20 and now a 71. I saw a plan I could copy on the web, sourced the parts, laid out a 1/4" aluminum chassis and had it powdercoated, started soldering, and then read a post on a forum from the builder that he never could get the hum out of the design. I wrote to him, he updated the schematic on his site showing how he went to DC heater voltages, and I started on the 20 while the additional parts got ordered. I did get the power transformer replaced in my 45 amp, something I've been meaning to do for the past 10 years after it burned up when I was on a ship in the Persian Gulf. My Khorns have been calling me lately saying "Send us some trons". Some day I'll get around to recapping my Dynaco FM-3 also. Tex, I hope you tested the ESR on those old caps of yours.
