[Hammarlund] HQ-150 Line Bypass Caps Needed

[Bill Stewart]

At the risk of running this subj. in the ground, let me ask one more question. 
What governs the capacitance/voltage spec of the line bypass capacitor? I have several Hammarlund  rcvrs and the values vary from .01uf used on the HQ-100, 110, 150, 170; .05uf used on the HQ-120X & 129X and .022 on the HQ-140X. And the voltage ratings run from 500V (HQ-120X & HQ-129X) to 1.4kv on the others. Some of these rcvrs are similar, but they use diff. values. I assume the capacitor voltage ratings used were for DC, but substantial enough to handle 3 or 4 hundred vac (have never noticed any ac ratings for these capacitors). 

Tnx, Bill, K4JYS
