1. [Amps] filament voltage dropping?? (score: 1): Author: mikflathead@aol.com; Date: Sun, 11 Jan 2009 18:13:59 -0500; Are there any advantages to dropping on the primary side or the secondary side ? This is on a K2RIW style amp for 432 mhz. The tubes are a pair of 8930s. I need to go from 6.3 to 5.5 or so. Mike ____; /archives//html/Amps/2009-01/msg00087.html (7,171 bytes)

Get a large (50-100 watt) adjustable resistor and put it in series with one side of the primary winding. Adjust the slider to the desired volt; /archives//html/Amps/2009-01/msg00089.html (8,162 bytes)
