I have a PCC85 TFK valve where there is some black discolouration visible on the glass.
Is this “normal”. I removed it from my amp when I saw this, as the PCC85 is cheap enough to replace, but is it worth me keeping it as a spare, or should I bin it?
I don’t have a valve tester, and I am sure postage to get it tested would cost more than a new valve.
I will try and get a photo of it, and post it later.
