1. [Amps] choke - cap filter network in PS (score: 1): Author: "Zeitler, Lane LT, FST-1" <zeitlel@cpr3.navy.mil>; Date: Tue, 23 Mar 2010 04:36:19 -0800; I have noticed that the older amps that use a choke input filter network such as the old Henry amps use a small value for the filter capacitor. My old Henry 2K used something like a 10uf oil filled c; /archives//html/Amps/2010-03/msg00494.html (7,100 bytes)

If this is for a Henry 2K: Probably a lot of bright lights and smoke with the 3B28's. Just the big cap and no chok; /archives//html/Amps/2010-03/msg00495.html (9,159 bytes)

That's the way I like to do it. -- Ron KA4INM - I'm proud to be Chuck's p; /archives//html/Amps/2010-03/msg00497.html (7,635 bytes)

So the caps available today were not around back then. 73 Hardy N7RT _______________; /archives//html/Amps/2010-03/msg00498.html (8,979 bytes)
