Hi guys,

I just bought two of the 6CA7. Both of them show borderline Grid Leakage, and some H-K Leakage ( heater to cathode).
I’m being told there is an acceptable range by some folks, while others say zero leakage is the target. I’ve never had a problem like this with any other tube, so I’m at a loss as to what to think.

Placing a funky tube in my new amps is not an option.

What say you all?

Thanks
