PYE CR/AC capacitor types
I'm not far off finishing this set however the schematic has several capacitors on it labelled as non inductive will fitting standard 630v Poly's make a jott of difference in a set of this age ( 1934)

Re: PYE CR/AC capacitor types
Unless they are in a tuned stage (where they probably do not need changing) there should be little difference.

Re: PYE CR/AC capacitor types
The PYE service manual states that C4, 5, 6, 8, 13, 17, 21 & 25 should be non-inductive.
Most of these capacitors are either HT (anode and screen grid) or AGC decoupling/bypass capacitors. In most radios they could be replaced with ordinary polyester capacitors. |
