Rectifier tube type #83 – BALANCED!
Made by General Electric
For many Hickok and B&K tube tester models (600, 600A, 752, 752A, 800, 800A, 6000, TV7,I-177-B and others)
These are the exact original tube types as used in the testers!
Please ask me if you are unsure if the tube will fit in your tester.
This tube you should have at hand, because it is the most stressed tube in the tube tester, which rectifies the plate voltage.
Please do NOT use any other tube, also not the standard unbalanced #83!
And in NO CASE use the silicon diode rectifier replacements you find at Ebay and at the internet. These have a different characteristic curve and will give wrong readings.
The silvery shiny layer inside the tube is quite normal and no reason for a complaint.
The tube was tested very good and matched for balance.
The tube is NOS (New Old Stock, never used) and NIB (New In original Box)
We also have other special tube tester parts on stock. Please ask us!
