HealthKit SB 101

I have a capacitor with a broken lead and need to replace. It is a 12 Pf mica but does not list the voltage or tolerance. It is connected between the neutralization capacitor and the final tune capacitor. Anyone know what the voltage and tolerance might be.

The DC voltage is blocked by other capacitors in the circuit, so the only voltage to be concerned about is the RF voltage. For 50 ohms (matched) that would be 71 Vrms or 100V peak for 100W. Allowing for SWR variations and other 'oops' factors, 500V should be fine. I'd suggest Mouser part number 598-CD10CD120JO3F.

Thanks Tony, that is what I thought. I am extremely new at this so I wasn’t sure.
