Also, buy yourself a tube tester. They are always for sale on YouTube. The internals are very simple. All you will need to replace is the electrolytic condenser. Leave the few resistors, some are precision and affect the readings. I have 3 of them, just in case, LOL ! If you see one that you are considering, just ask about it. I'll be happy to advise.
