Capacitor identification request
I really just want an idea of the working voltage, so I can replace a screen grid decoupler with it. I cannot find the manufacturers symbol in any listing - it's pretty old, probably from Decca Navigator days. It does still read 3000pF.
Thanks |

Re: Capacitor identification request
2% suggests it's mica.
the voltage rating could be anybody's guess but maybe 150-250v. It's a type usually used in RF/IF tuned circuits, only seeing signal voltages and far too expensive for something as humdrum as screen decoupling. Save it and go with a disc ceramic. David
