Oops forgot about the Zener. Unfortunately the 3 sams for CTC125
I dont have. No training manual either.
The coil I was thinking of fed the MSC & was for tuning voltage
IIRC. Not sure if these had it but I think it was CTC120's
had a bunch go cold.
Worth some time, twas a good set & dont take up much room
or eat to much.
