EAT ECC-88 Cool Valve
Tight Tolerances In these tubes the tolerance of electrical ratings are reduced in comparision with standard tubes. Vibration and Shock Proof The tube withstands accelerations of 2,5 g at 50Hz for lengthy periods and momentary shocks of 500g for short periods. Cathode Free From Interface The cathode establishes no interface even in cases where the heated tube is operated without plate current over lenghty periods. EAT ECC-88 Cool Valve Data:
