1. [Amps] Correct Method Of Hi Potting An Electron Tube (3CX-6000A7 / YU-148) (score: 1): Author: "jim.thom jim.thom@telus.net" <jim.thom@telus.net>; Date: Tue, 11 Jul 2023 08:24:48 -0700; On the 3CX-6000A7 triode, the tube is 1st hi-pot tested between the anode and grid (and a temp short between grid and cathode). Then the polarity is reversed. Leakage should be < 5 ua in both cases.; /archives//html/Amps/2023-07/msg00002.html (8,181 bytes)
