Default Re: Ferrograph Reel Expert Help Please!

You may or should replace it anyhow even if it measure OK that does not mean it is not leaky. More important if it is DC blocking capacitor in the grid circuit than in this instance but it is well old lets face it.

If a capacitor is leaky and is a grid circuit it messes with the bias voltage on next valve, can cause red plating and over run valve, burns out transformers and when I mean leaky that is DC volts. You may want to think about that when looking at the tape amplifier.
