Default Re: AVO CT160 Valve Tester. Value and calibration?

In fact the 2 CT160's I used to have both came from Gerry. The 2nd had had a bodged op-amp jobby done on it by a customer, then returned. Hence dead cheap. But then I ran it with a 444uA meter out of a phooked MK1, via a op-amp from Jeremy O. Worked a treat.
Gerry, Jeremy, Mike B, and one or two others, set the benchmark for trusted AVO VCM dealings in past years. Nowadays, in view of certain recent missfortunes to two or three VCM's, I feel inclined to advise folk to thoroughly examine the provenance & reliability of these expensive items.

Regards, David
