Questions about tubes and gear that glows. FAQ

Varies, but, yes ,in the ballpark.

I only paid $200 for mine but that was 5 years ago. The TV7 Army-JAN tester is also very nice. They all are getting pricey. The Daven company also made a good JAN tester that sometimes appears. The Weston 981 was also made for the government as a 798 I think. Much of this government stuff reeks of fumes of some chemical that they used to impregnate the power transformer and has an umpleasant smell. The B&Ks, EICOs and Sencores all seem to show up worn out. The Hickock 750 series is very nice (green panel with engraved switch numbers). You want a transconductance tester than has a built in oscillator at around 1K and also a variable pot of delivering screen voltages. There are many emission testers on the market that only test the condition of the cathode and whether all of it's coating is still in tact. That's all they test for. A transconductance tester is what you want and delivers a real test of the condition of the tube.
