[ARC5] Tube Equivalents VT-52 VT-62

[Robert Eleazer]

I have two VT-52 and two VT-62 tubes that appear to be NOS.  I want to sell them for a friend of mine but I want to test them first.  My tube tester does not have those tubes listed in its test data.  The tester also does not have a suitable socket so I'll have to build an adapter, probably an octal plug with some alligator clips on wires.

Can anyone suggest a roughly equivalent octal socket tube that I could use the settings for in order to test these tubes?

Thanks.
