I went to the site mentioned a few days ago with all the amp pictures, http://www.angenent.org/W7IUV/amp-pix.htm and noted that most of these put the vacuum variables horizontal with the tuning shaft
? Builders who use horiz. mounting apparently did not read the Jennings catalog. ? Semi-excellent. Four 8877s are way more expensive than one 8171. They require twice as much drive and they do not h
Mounting Position- Units may be mounted in any position. When large capacitors are mounted horizontally, both ends should be supported to prevent excessive stresses (vertical mounting preferred). You
Bertha used two ceramic vacuums, stood on end with the silver plated coil between them (she's a mono bander). The caps were driven with right angle drives and turns counters. That's why the turns cou
In a frequency where the box ground path could be noticeable the large HF vaacum capacitor would be already out of matter because of their stray inductance. Practically speaking, the output circuits

Not to start a long thread about this but.... Which Jennings catalog? My 1980 edition, which covers all the vacuum caps I've used, specifies ANY mounting position. 73, Marv WC6W * ___________________

As does mine Marv, my catalog says "any position". The only warning is to support big capacitors at both ends. 73, Tom W8JI w8ji@contesting.com -- FAQ on WWW: http://www.contesting.com/FAQ/amps Subm

After getting the comments from Rich about this, I've gone over to vertical mounting, and found (fortuitously?) that I end up with far more sanitary layouts and easier mechanics. However, I am motor
I use a sub-front panel and mount the capacitors directly to it. The input and control circuits go between the sub-front and the front. That way I can work on the input or control/bias/metering circ
As they say, there's more ways than one of skinning a cat.....I think that especially if motor driving, vertical mount can (not necessarily has) have advantages. 73 Peter G3RZP -- FAQ on WWW: http://
