Any Question Please ask
Please note: These tubes may be NOS or test NOS but will actually have a few hours of use from manufacturer or due from testing through 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 and is been listed as NOS/NIB
- Therefore, when we stated as "NOS" in the title are only believed to be NOS and no warranty is made that is a true NOS tube. It’s anybody's guess how many times any of these tubes have traded hands.
Please expect the tube to have a small amount of used *
All tubes will be retested before shipping.
On a mutual conductance tester=GM
Either on Hickok models 6000/A,539C,752A, 533A,800,VT-7b/u,I-117 military tester or a B&K 700,747
1. Complete visual inspection
2. Allow 1 minute warm up time
3. Test for actual real-life mutual conductance (life) of the tube (including any shorts,gas and leakage)
4. Test for proper gain of the tube (perhaps the single most important test of a preamp tube.
Rectifiers and Diode tubes do not have Transconductance values
If some prove defective during testing, and we are unable to provide a substitute acceptable to the buyer, an immediate no-hassle refund will be issued.
Please take this consideration
If I state any values they are for a guide only.
Two testers are never the same. So this shows what I get, and what you get may be slightly different.
