 Please note: These tubes may be NOS or test NOS but will actually have a few hours of use from the manufacturer or due from testing from time to time on them.

Two testers are never the same.  So this shows what I get, and what you get may be slightly 10-15% different.

If I state any values they are for a guide only.

No guarantee is made that any tube will test to a specific value in the buyer's tube tester, most all tubes are tested on at least two tube testers

This because of the variation in line voltage, different bias, and circuits.

All tubes have passed the Gas and short tests.

Regulator, Ralay, Rectifiers and Diode tubes do not have Transconductance values.
