1X2: Difference between revisions

Latest revision as of 02:24, 19 September 2023

The 1X2 (European: DY80) (P/N 154-0005-00) is a high-voltage rectifier vacuum tube with a B9A (Noval) miniature 9-pin base and an anode cap.

Its maximum inverse voltage is 15 kV and the maximum forward current is 1 mA. The filament operates on 1.25 V, 200 mA.

The 1X2 tube is used in the 565, 507, and 517 (420 HV supply).
