    What is the bias tap voltage on a deluxe reverb. I want to get the right rating capacitor for it. The schematic calls for 50 volts but I can't read the tap voltage on my phone. Thanks!

    I think most go up to 100v now days for that cap on the little bias board... if that's what you mean...

    The bias tap is usually 50vac then half wave rectified, common to replace the bias cap with 100uf/100v cap.

    The schematics have -35v with a 25uF/50v cap. The reissue schematic it is -35v with a 22uF/63v cap.
    I would try for a 63 - 100 volt rating.

    100volt 105℃ capacitors are readily available and will last.
