DESCRIPTION:

Philco 6J5 Vacuum Tube Metal Tested Good

Condition: used

Some boxes are brittle, or have imperfections, starting to crumble if they are not salvageable will ship in a plain or different brand box 

 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. A truly NOS tube will have excellent getter flashing condition, no dirt/grime, usually in the original box, and no filament deposits and has never been tested. Please expect the tube to have a small amount of used

Since vacuum tubes were made 30 - 70 years ago New Old Stock or Used may have cosmetic evidence of age.  This includes poor print, oxidized pins, faint discoloration, or poorly box

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.
