The vacuum tube tester
#6

In any case, it is an excellent tester. I am not sure how much advantage you get with 800, or 6000, or even with 539B (which is of course the king of them all) - the thing is, you are buying this to fix radios and you need some minimum info which is well taken care of by 600, and do not necessarily need all that extra info from 539B, which is also twice the price.
I would not like the cheaper testers that are emission testers but not transconductance ones.

My vote is for 600 or 800.
