I would say the amp is working like "Gang-Busters," Dan. If you have a manual, you will find that the length of coax between the exciter and the amp is very critical in length to obtain optimum uotp
Also, Millen is alive and well in MA. They make beautiful drives with multiple mounting capabilities. They ain't cheap...($75) but they are encased to keep the crud out of the gears. (((73))) Phil,
Using the "stock" 100 ohm 25 watt metal-clad resistor in my MLA-2500B, the input VSWR is 1:1 on 160-10 meters. Even if it has an inductive component it is hard to beat for a perfect match to the exc

I have several suppressors made by Eimac for 3-1000Z's and 4-1000A's. They use large carborundum resistors and silver plated strap or large bus bar wire. Most commercially made suppressors for large
Unfortunately, the average casual amp home-brewer has nowhere near the test equipment necessary to determine the need for a suppressor in his particular lay-out. He is constantly in search of a devi
Henry reduced the dissipative burden in R-supp 100% in the 8-K Ultra by adding chrome plating to L-supp until the right R/L ratio was reached for the 3CX3000A7 layout. Several scoffed and threw rock
You really only need one tube, as it will put out as much as the pair of 8875's. To take advantage of the potential of a pair will be nullified by a power supply melt-down. It is easy to get screen
vac. cap. tinks can barely be heard. Big bangs are loud. The accompanying flash comes from the HV circuitry. The tink can barely be heard because it is a current limited arc. Does anyone care to sac
There will be plenty of room up front when the old tune C is removed to install more robust load padders. Woe be unto the manufacturer that uses blowers that make noise! This is a no-no in the think
My guess is that the switch contact burned/arced before it ever LEFT the position it was in. One usually does not jerk a tune C around, so the hand movement was probably slower and less forceful tha
I maintain that a 100% fudge-factor for R-supp is good engineering practice. (((73))) Phil, K5PC -- FAQ on WWW: http://www.contesting.com/FAQ/amps Submissions: amps@contesting.com Administrative req

Hi Folks I have a quantity of 10,000 pf feed through caps, Most of the designs for amplifier I have seen call for 1000 pf feed through can i use the higher value ones that i already have ????? Commen

Boy, you can say that again!!!! Better circuit, indeed. Unfortunately, I have been retained to rebuild one that has been crispy-crittered. There is very little room to work with in such a small box.
I remember in the old days before variacs and test meters that my "Elmer" used a light bulb in series with one side of the a.c. mains to limit current an act as an indicator. If the two windings are
