Re: Bush A.C.91
Where is the best source of information on the modern equivalents for capacitors in vintage radios?
For example, I need to replace the 32μF 275V H.T. Line Smoothing electrolytic capacitor but can't find one with the equivalent voltage. I know the rule is to go high but how high on such occasions.
Similarly with the tubular capacitors I know that the existing 0.05μF 350V will be replaced with a 0.047μF, but what voltage is appropriate.
Finally, what should the voltages be for these capacitors: -
0.1μF, 500V Mains R.F. By Pass capacitor - X-Type
0.0005μF, 500V True Earth Isolating capacitor - Y-Type
More generally, apart from experience, how do you determine when a capacitor should be X-class or Y-class??
