The meter on the left shows the plate current when grid voltage is most negative, while the meter at the right shows plate current 523 the grid signal voltage most positive. Ask a question – opens in a new window or tab. The A unit is older, hiclok data is less available.
Englewood, Colorado, United States. The top meter on Dr. When P1 of the 83 is positive at the same time that the cathode end of Secondary 5 is high, the Gm meter will want to swing toward the low end of the scale.
This is a must, if you test a lot of 12AX7’s! The TV-7 is very similar to TV but has flip-chart hicjok data in the upper lid of the unit. The B and C units have a “VR” function to give a quantitative test on voltage regulator tubes like 0A2.

It allowed Hickok to produce the best-selling dynamic mutual conductance tube tester on the market until the patent expired in The keys to the performance of the Hickok circuit are accurately calibrated potentiometers, a sensitive and accurate Gm meter, and the absolute predictability of the phase relationships of the voltages produced by the secondary windings of the power transformer. It is classic military construction with potted transformers, ceramic sockets on the minis and octal, and hermetically sealed caps.
Tube Tester 532P
At this point the cathode and the grid are at the same potential, in other words, zero grid bias. Here is a Hickok in a Very nice metal case that needs repair for full function, but works well on 5U4 And other rectifiers. The is a beautiful machine. As the wiper on the bias pot is adjusted toward R the cathode becomes positive in relation to the grid.
This amount is subject to change until you make payment. Since the Gm meter can’t swing back and forth 60 times per second, it will settle in at the average of the two readings, thus providing a true mutual conductance reading for the tube under test. Has sockets up to 9-pin mini. Back to home page Return to top. The TV-3 is a very cool tester. Has switch selected gm ranges like A.
