First, please remember this is a SERVICE.  No tube or tester is being sold.

This service is to test a SINGLE tube, of one of the following types:

203, 203-Z, 211 aka VT-4-C, 242-A, 503, 805, 838, 845, 8003, PJ-12 and ZB-120

If you have more than 1, please enter the amount into the QTY before adding to your cart.

I will use my equipment (TV-7A/U calibrated in 2022 by Dan Nelson, THE TV7 expert) and a specially made adapter.  

This test can verify:

1) Emission Leaks
2) Shorts
3) Mutual Conductance
4) Filament

If you have one of these tubes, and plan to use and/or resell, this is a great way to test before you do.

For resellers, perhaps you have these tubes, but no way to test?  I can test, affordably, and present you with the findings.  

Shipping is on you to get to me (I recommend using a Flat Rate USPS Insured Package).  I will do the same when returning.  My shipping charge for returning tubes is a flat rate, if you send me 1 or 100 tubes, it is the same.

I will send to you using USPS Priority Insured.
