Extremely rare Amperex Long Plate Foil D-Getter 7316 vacuum tube (= 12AU7/ECC82).$150 for one tube. These are considered by many to be the best of 12AU7 type tubes. They are made in Holland in 1958 with D-Getter and Large Foil Strip. They have Ct0 etched code near the bottom of the glass. "Ct" indicates 7316 type tube.
"0" is batch code and indicates the very first batch. They also have etched code of "Delta 8" (made in Heerlen Holland in 1958). Most are labeled as Beckman and have some of the label erased from handling. They test very strong for years of trouble-free service. Tubes are fully tested by precision calibrated Hickok 539C tubes tester. No shorts, leakage or gas. I can easily select matching sets in terms of date and measurement. I will send you photos of selected/matched tubes with actual measurements upon request. I guarantee excellent performance, so buy with confidence. If you are not satisfied with my tubes for any reason, I will issue full refund for your purchase price. Payment by check or money order only (no Paypal please). Local pickup is always welcome. USPS Priority Mail shipping within US with tracking is $9 flat.
