Yes. Do it in your own amp.

Install the tube and run the heater and fan only, for a day or two. Very simple.

Before you do that, if you have a 1kV Megger, you can test the cold tube, between all elements, for leakage. If there is a problem, it will usually show up with that test.

If there is no problem, You should be pretty safe in plugging in the tube, without the conditioning process.

I bought a NOS Eimac 4CX1000a . Looking at the tube, ir shows no signs it has been used. Is their a place I can send the tube to have it Gettered and tested before installing in my Acom 2100 amp ?
