I need to give up on this one, I have more tube comps that I can ever use at this point and the project list must be trimmed.
(2) PM660’s built, ceramic sockets in 5687 positions, beefy Dale resistors in the important spots. Stock parts values in all positions. Amps tested on the bench to measure performance, shelved since then.
PSU built with exception of IRF820/IRF840/LM317/LM337 - have spares, need insulators. Stock parts values in all positions.
(2) [silent:arts] HWBP36 bypass PCB's
American group buy toroidal power transformer - Avel Lindberg AV-087539. 115V or 230V primary.
Complete stepped attenuator resistor selection should you decide to go that route.
Filament bridge rectifier.
50W 1R adjustable resistor with mounting parts for filament supply. The best way to set the filament voltage.
(2) dual 50K audio pots for side chain amp control with (2) slugging resistors to correct the overall value.
(4) 10K linear attack pots. Why 4? I couldn't say, but there they are.
(2) 5K audio screwdriver type meter adjust pots
Edcor selection: (6 lbs)
(2) WSM600/10K and (2) XSM600/10K, or (4) XSM600/10K. Your choice.
(4) XSM10K/600
8 total transformers offered.
4 x 6BC8/6BZ8 tubes
4 x 5687 tubes
$495; less than cost, you get my research and labor for free
Don’t want the Edcor, subtract $88
Don’t want the tubes, subtract $60
Plus shipping/insurance.
Outside of any mod plans one wanted to implement, everything is here excepting the following:
Gain reduction amp input attenuators. Follow the stock plan, use the Kingston M670 plan, use another pair of 50K dual audio pots.
VU meters.
Case
Connectors
Knobs
Power cable
Bypass PCB parts
Molex connectors for interconnection: I was going to hard solder all connections rather than use these.
