PLEASE READ
:
I use either a calibrated Hickok 539C, TV-7D/U, or for new design tubes a calibrated B&K 747. Test results must exceed the tester minimums by at least 10%. I attempt to match all the tubes sold in pairs to within 7% of the test readings. Because I don't know the operating condition of your equipment, tubes are sold "as is". I may have several of the tubes being auctioned, and may NOT use a photo of the actual tube.
There may be some larger type tubes that I do not have the equipment to test for other than filament continuity (I'll put that in the listing).
INTERNATIONAL BIDDERS:
Because I can only test for technical things like transconductance, gas, shorts, etc., I cannot test for things you might think you don't like (tone, response, etc.).
UNDER ALL CIRCUMSTANCES
: if you purchase any tubes
YOU
agree to be responsible for any return postage.
QUESTIONS?
please ask them before bidding.
