Oh...I meant "pF" of course (110nF would be that 0.1uF which I have plenty).....and I do have one (leftover) 600V 100pF cap from another Philco restoration prj (I think that was the 18)....but since those are expensive and I only had one....I thought that maybe those were micas and I would have one less block to restuff and 6 bucks less to pay (I remember they were about $3 each at 1% accuracy and #2 at 2%).
Oh...well.
I recently was thinking about the ripple current (I am about to write a thread about it) and I realized that in many radios we may be undersizing the ripple rating so I think I will be ordering some aluminum cans anyway, will order some of these also.
(BTW I found a great way to at least double the ripple rating for the DC filter caps).
PS. What tolerance were those originally?

Philco Model 16 wiring question

Thanks Morzh. So it appears I did wire it incorrectly and I have to switch the wires between pins 2 and 4.bobclausen — 11:36 AM |

No, it's not a problem, just during certain condition it could show up.
Yes, an internal tube short could do that too.
