Hickok 539B Tested and

This sale is for One Tube.

Several photos are to show that I professionally test every Tube for Sale.
All Tubes are Tested for Noise, Shorts, Leakage, Gas, 
Plate Current, Life Test, and GM or Transconductance (micromhos).

Hickok's 539B Specifications states that any tube over 
1150 micromhos is good to use.
On My Hickok 539B, this tube tested 
at over 2300 micromhos and Higher.


Although these tubes are labeled Amperex, 
I cannot guarantee who made them.

I can guarantee that this tube was thoroughly tested and had 
extremely strong Transconductance.
Twice the amount of Hickok's rejection specifications.
