    Offered is a lot of (4) 12AX7/ECC83 Twin Triodes.  Each is likely by Amperex.  Two are Amperex Bugle Boy types with matching printed codes of 1 07 (etched codes: 163/4012 appear on both tubes).  One is marked Zenith, its printed code is 907 and etched code: K6/48L and one marked "Electronics for Medicine" it has a 204 printed code and  165/49K etched code.  The tubes test good on the EICO dynamic tester, they show no shorts or interelectrode leakage.  Test readings for the Bugle Boy tubes are 120/125% and 140/125%.   The readings for the Zenith are 122/130% and the Electronics for Medicine tube has mismatched triodes with readings of 90 and 125%.  The good range on the tester goes from 80% to 140%.  These tubes have dark grey plates with top halo getters (the Zenith has a top getter of a D shape with a flat section opposite the support rod). Pick up the tubes for your own projects or for work upcoming. Suitable for Hi Fi, radio or amplifier use.  NO RESERVE!! GREAT PRICE!! Thanks for looking.
