There are other testers like this available. They test tube bias when in circuit. They dont measure Gm or emissions.View attachment 99468my browser sent this to me. I have not tried it. I am thinking about it. May buy it for a review.https://www.stewmac.com/luthier-tools-and-supplies/tools-by-job/tools-for-electronics/vht-tube-tester--amp-bias-meter/?
Are you looking for a bias tester or a tube tester that measures tube parameters and tube strength? I've been looking for a simple tester that isn't 50 years old.Great can you share some of them with the members? This one has an attractive price and bias.
A tad late maybe, but I bought something similar a few years ago (not sure if they are still available!). No built in dials, you need to plug into a normal digital volt meter, preferably autoranging. Two toggle switches on the unit, one to select the tube, the second to choose between Ik and Vp (an autoranging voltmeter saves resetting the DVM voltage selector between tests).View attachment 99468my browser sent this to me.

That looks like a rather nicely built tester at a very reasonable price Leif … I wonder if they would consider ( Be Mad Enough) building me a unit to specifically test full parameters for Transmitting valves specifically 813 and 814.I have 1 custom made for my selection of tubes used in system

Looks great! I have always fancied a device to check /match my EL34s. Would this really replace a traditional emission tester / matcher?I have 1 custom made for my selection of tubes used in system
