No grid voltage in model 20
#3

Using a Fluke 23 DMM for most all measurements. Resistance for coil #2 24
ohms for pri and 7 ohms for sec. Measured other coils but forgot to record in
my notes...They are not open or shorted I can tell you that much anyway.
No noise on the 2nd RF at all. Here is link to picture of variable cap and you
can see the compensating condenser, one on each stage. Leakage across
variable cond ? Not sure what you mean. Thanks for your time and assistance.
