Jim McShane is really excellent for buying current production tubes well matched. Brent Jesse and Andy at Vintage Tube Services are excellent for NOS - I mean when you get your amp back a decide whether or not you like it.
TVAD, on the resistor-as-fuse amps, it is unfortunate that one of the best sounding amps I have owned and ever heard operates like that - CAT JL2 - the designer thinks fuses screwup the sound - I sold the amp and bought from a fella who thinks that not have an amp fry when a tube fails is important.
