(score: 1): Author: "BEHIELS JEAN-PIERRE" <ON4AEF@base.be>; Date: Wed, 19 Jan 2011 09:18:59 +0100; Hi, I am busy to fireing up a old Kenwood TL922 amplifier(1985). I have already build in a start-up system for both filament and high tension power supplys by means of two homebrew timers,and a serie; /archives//html/Amps/2011-01/msg00182.html (7,651 bytes)

I am quit making my own start delay into a old (1988)TL922 amp. I made two primary transformer start up delays for : A for filament supply.

One method is to measure voltage drop across the 47 ohm resistor. If you are doing that with a typical digital voltmeter it will display a; /archives//html/Amps/2011-01/msg00210.html (13,982 bytes)

I really don't need this accurate measure around this 47ohm/50W resistor,but I have done due the fact I saw he has coming up very hot !

All you need to do for the filament is limit the inrush current while it's cold. A half-second sho; /archives//html/Amps/2011-01/msg00213.html (14,018 bytes)

(score: 1): Author: Mike Tubby <mike@tubby.org>; Date: Sat, 22 Jan 2011 10:25:35 +0000; It might be worth powering up the amp with the tubes out just in case you have a problem with a tube. I had one tube that was very low emission but was able to re-activate it using the circuit descri; /archives//html/Amps/2011-01/msg00223.html (19,285 bytes)
