OUR EQUIPMENT

AMPLITREX AT-1000

Quite easily the Rolls Royce of all vacuum tube testers.  The AT-1000 is a fully programmable, solid state unit that can test in either FIXED or AUTO bias.  We have a full range of adapters which will accommodate most pin assignments including, loctals, 9 and 12 pin Compactron tubes as well as an adaptor for Type 211/VT-4-C tubes.

TV-7 C/U

Dan Nelson Calibrated !!!

Manufactured in Canada (C/U designator) by Stark, this tester parallels the TV-7 units made in the U.S.A.  The C/U model is complete with the European (Stark ED) adapter that will accommodate most European designed vacuum tubes.  The TV-7 is a highly sought after unit that retains its value and is certainly the benchmark for all vacuum testers on the market today.
