David,

I have a stock of the Ohmite version of 10k 50 Watt pieces with extra slider clamps. They serve well.

Norman,

I believe you are correct. The Candohms used in the other chassis' I've seen run fairly cool.

The Candohm resistors usually fail due to corrosion between the lug and the resistance wire causing loss of continuity, not due to overheating.

I have replaced several of the same canohm units Scott used on the Phantom, Sixteen, Masterpiece - same values. That particular part was not robust enough. 

I like to use the big 8000 ohm ceramic resisters with the exposed winding on one side and 4 of the slider clamps  - great if you can find them.  

The redesigned 1940 Phantom 6L6 amp was evidently intended for both the standard and FM version.

I find having an actual Riders Volumes beats any other medium for clarity of print, and glad i picked up Vol 1 to 15 years ago.

Thanks David,

Robust they are however, I still install my share of replacements ;) My set of Riders is incomplete. The online text was not clear enough and I like my B+ spot on.

Scott talks about the power supplies being "robust.

Bill  - There are 3 Phantom Diagrams in Riders vol 14 and 15.

All three show the B divider high  1975 ohms, 780,  980,  3875 to ground  --  located in the receiver chassis.  

These values are true the redesigned 1940 FM Phantom and  Amp that you have with 6L6 s and 5U4's   ---   Riders 14  page 3,4 which is an double size fold out.
