I never tried driving the grid but in gg it is close to X15 when motivated by a pair of UTC CG310s on the high taps. I've read your article a number of times on the on you did Rick. Frank wa1gfz R L

To thrive, like a TV soap opera, a discussion group needs a protagonist and an antagonist. Tom and yours truly are such. Without Tom, my guess is that there will be a lot less entertainment value. R L

Gents On these 3CX-6000's and also the socketless version [ YC-243], I fool with from time to time, Eimac/ Svetlana state's the grid diss at 225 Watts CCS. [3CX-3000A7 is also 225 w CCS grid] Now,

The Z looking into the primary is a function of what's on the secondary. Silver soldering the remaining strands with 6%-Ag, 94%-Sn (221?C) solder is helpful.

In grid-driven service, the 4cx3000A has a power gain of c. 60x.

Tnx, PAUL. Sounds like two Panasonic switcher supplies would run an 8877 om SSB. R L MEASURES, AG6K. 805-386-3734 r@...

Yup Mike, They all went to Frank because I have a box of 4CX3000As. They also work well in GG mode and have a bit more gain than the 4-1000A. wa1gfz Mike Sawyer <w3slk@...> wrote: Frank, I

Earlier today someone mentioned the top band reflector. I love 160 and can't wait until the bands get quiet enough for it to be productive. However I have a lot to learn about building some kinda

Very interesting Rich. What would be the regulation of this switched mode power supply? Cheers, Dick powered units switcher HV. power

And what's the alternative? I should "out" him? That's not my prerogative, either. I have been a member of amps since its inception, and while I disagree with prior restraint of speech, I think its
