[R-390] R-390A IF deck caps in T501 or T502

[Jacques Fortin]

Hi Larry,

On the T501/502 I have, there is two caps for each winding, one ceramic
"dogbone" style that I suspect to be a temperature-compensating one and a
mica one,
The mica ones are coded 200pF, so I guess that what you read on yours can be
interpreted as:
115E: this have to be a product identifier and 1G03 can be just the end of a
full marking 201G03 = 200pF, 2% tol, 300V working.
Is there a brand on the casing of those caps ? Micamold ??
My recommendation is to change the mica ones only for new dipped mica caps.
It would help if you have a capacitance meter, even a cheap one...
