Hello..

I have a Mullard 12AU7 that tests good for emissions but when I run a grid leakage test one side shows questionable, and the other side shows bad.

What will this tube do when I use it in my crack?

I'm thinking that it will be really noisy.  I have one of those too, bought it on eBay.  It hums badly.
