Of the two electrolytics, I'm sure I can replace the 16uf with a 22uf but what about the 12uf? The closest is either 10uf or 22uf. I suppose I could tie a 2.2 and a 10 together. Suggestions?
There are a few silver mica's that are 1250 and 5300pf. I can replace the 1250pf with a 1500pf but what about the 5300pf?
Is there a list of typical replacement cap values for this or similar models. Most of the data I found on Philco repair bench is for older models.
I'll be ordering metalized film for all the tubulars and silver mica's for the mica and silver mica. I've found ones in the 450 to 630V range.
Thanks!
From what I heard the old rule of thumb is meet or exceed the capacitance, especially the larger ones. I've been using 22 mf's to replace anywhere from 12 mf on up. I had a simular radio like yours, used 2 22mf's as replacements for each. Works great.
