1. [Amps] Cold neutralization with high voltage bias? (score: 1): Author: Guido Tedeschi <guidoted@gmail.com>; Date: Tue, 7 May 2019 14:37:01 +0200; Is it possible to neutralize a grounded cathode tube PA for minimum output signal, if the Bias voltage is set to maximum available value (ex. -80V for a pair of 6JS6C) and the drive is limited to les; /archives//html/Amps/2019-05/msg00010.html (6,741 bytes)
2. Re: [Amps] Cold neutralization with high voltage bias? (score: 1): Author: Guido Tedeschi <guidoted@gmail.com>; Date: Thu, 9 May 2019 19:53:19 +0200; Hi Ron and thanks for the answer. I know that the better method is neutralize for minimum feed through of the signal with no screen and plate voltage applied (also disconnecting only the heater volta; /archives//html/Amps/2019-05/msg00016.html (9,276 bytes)
