[Heathkit] SB-102 voltages

[GARY HATTAWAY]

All,
 
I'm working on a SB-102 that uses a 6HS6 as the RF amplifier...after a few minutes, the AGC begins to misbehave, and the s meter swings below zero. These are classic signs of bad (leaky) RF or first mixer tubes. I've checked V-10, 11, and even replaced them with known good tubes. I've checked all the resistor and cap values around the RF amp circuitry and found everything within specs. I can substitute a 6AU6 for the 6HS6 and the receiver works pretty well, but then the s-meter tends to rest below zero on 15 meters and above. It's fine on 80-20.
 
Does anyone have nominal pin for pin voltages recorded for this rig?
 
Thanks,
