The #83 is
a mercury vapor rectifier tube which is used in Hickok and other
Mutual Conductance tube testers.
Some dealers recommend and offer a #5Z3 or a solid state
device as a replacement the #83. I
disagree on both accounts. The 5Z3 is a better choice for replacement
over a solid state device, but there is a reason that the #83 was
chosen by Hickok, B&K and other manufacturers. More info on
this subject can be found on my web
I am sold out of my good used #83's and
offering a limited quantity of NOS tubes from various manufacturers.
All are vintage us made brands.
More info on tubes,
manuals, tube testers etc:
Instruction manual copies and obsolete tube set-up data available for
many of the old tube testers,
inquire about availability and pricing.
