21fjp22 or 21fbp22
So are there any 21fjp22 or 21fbp22 crts around used of course I’m looking for one . Or maybe even a trade for a brand new 7jp4 in the original box numbers match as well as the serial number both numbers from box are on the tube.

If you are coming to the ETF check my thread on it I have one I can bring, but I won't ship it.

The tube I have does check good but I really don’t know if the life test is that accurate or can it be relied on for getting a good idea how good a tube is. If the life test is accurate then is there a guideline on how long to let the heaters heat up befor testing the life function.
