I have a few NOS, in the box, 2-01C diodes used in the RF probe for
the HP-410A/B VTVM. This is the tube that usually keeps one of the
best VTVMs ever made from being 100%. The cost of this tube is over
$30 on the net. I'd like to trade for equivalent value tubes such as
811A, 6293's, 3TF7, etc.

If interested please email be at
