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.
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.), so if you purchase the tubes
YOU
agree to be responsible for any return postage.
