I can't resist this one. You open it up--the Silver Fish have eaten your manual, the spaghetti tubing is brittle as spaghetti and disolves in your hand, the terminal strips are so oxidized they requi
I think you could have the RF deck on the power supply or separate it with a cable and the power supply would be under the bench or somewhere else. Go to Radiodan"s website. He has the blow-by-blow d
Wow. I would be afraid the fire that one up. It looks like the plate vac variable and coil are at plate DC + and the blocking cap is after the coil. That means the vac variable has to withstand the i
Actually a match is dertermined by the ratio of the antenna Z to the tranzmission line Z. The generater Z has nothing to do with it. At least that is what I remember. So all these amp specs are irrel
I have a 3CX800A in an SB200 redone for 6 meters and turned it on for the first time in about a year. When I depressed the foot switch, the plate current went to 800 mA with no drive. So let up on th
Hi All Emtron was there and if you want one of their amps, contact them direcrtly. It's a "we can sell you one and you are responsible for the (power) outcome" type of deal. They have the high power

How do you capture every leaf that falls from a tree during Autumn? The cat is out of the box. He might as well copyright the voyage of 1492 of Chris Colombus. Well tell me the difference between cop
Everyone, I think Harbach has bought all the intellectual property of Peter Dahl. I have not seen any ads, promotions etc for Peter's old products. Nothing at Dayton this year. Anyone know what's goi
To all : Melting antennas is a very good sign since I am the last one to relate this story. Circa 1957. San Fernando Valley, CA W6HX, Ted Gillete builds a 20 meter amplifier for W6YMD using 2-- 4-100
Bill, I was sticker shocked myself when I wanted to buy a replacement 3-1000. I talked to a manager of Eimac in Salt Lake City who basically said the 3-1000 was on its way out and the tooling, time,
Check Allied, Mouser, Newark etc for amplifier "bricks" as we used to call them. They are off the shelf power modules that need input, output & a power supply. And a heat sink..... GL Hardy N7RT ____

Speaking of 8873's, anyone know what the cathode driven input Z is at 50 MHz? I am converting an Alpha 76 to 6 meters. The literature is not forthcoming with such info that I have been able to find.
Jim, Have you tried a different SWR meter? It could be that the directivity of your meter is poor and as you add coax, the voltage maxima changes position on the coax allowing a small amout of input
Rick and all, I called Jerry once (out of frustation) and he really answered the phone! Well we certainly did not talk about history but he was a very gracious gentleman that explained a misconceptio
I have just rejoined the amp list after a few years and am wondering if the diode equalization question was ever resolved. I am building a new bridge HV PS and it uses 12 diodes per leg. Rich Measure
Hi All, Well everyone is certainly getting the mileage out of my original post, but I really want to thank everyone who responded. The concensus is just go with the 5408's and everything should be fi
But the caveat to this whole question was he stated that the amp was to be used on 20 to 10 meters only. But excellent comments about low band operation. I have been "burned" by inadequate RF choke X
