Obviously door stops but easy to find pictures. The seller may be breathing NOx while typing NOS.

Funny question. A few web site "authorities" discourage working with amplifiers simply so they will make more money. Same guys who bad mouth CBers are working on their tube amps for ca$h. Others are married to manufacturers. One dude sees nothing wrong with a grid driven 4CX250 for VHF...

Last time I looked the only really easy Russian tube to work with was the GS-35B. Ceramic tetrodes usually will not work by tying the control and screen grids together so that is out. The higher dissipation triodes seen for sale from Russia are medium to lo mu and will not behave well in...

Look for 575A rectifier tubes and hi-potted fil xfmrs.

Some older Orr radio handbooks are available for free download. The Radio Handbook 15th edition | Free eBooks Download - EBOOKEE! Reforming capacitors can be done with any HV supply hooked to a variac. Ramp up to working voltage slowly and watch current. Any heating means the ramp is too...

You might get more enjoyment from CB by learning to speak Spanish.

I noticed a similar thing with Icom 706s about 6 and 7 years ago.

But remember to make the tube anodes glow once in a while or they will zorch over.

Here's another really good TS-830 site: http://www.n6wk.com/kenwood/TS-830-Survival-Guide.pdf

Works just like you said. The other methods provide some gain compression however.

And works OK on an old Hallicrafters low end model from before the war:biggrin:

Who's debating the modification? It looks like a modification to me. OK? 200 khz of splatter eh?

Turn up the S-meter pot and volume control. That will have the same effect as a receive preamp only with slightly better SNR. Youe noise blanker will still work and the radio's front end will have more dynamic range. The only time a receive amp improves communication at CB frequencys is...

Hi Bert, Getting on the air cheaply seems to be much less important than it was years ago. The new guys I hear appear to be having the most fun buying and trading up. Of course there are always exceptions. Thrift is a time honored ham tradition! It will take a few more components than...

Maybe he needs one of these Fake Hand in Sleeve Or how about a small 30-75 pf capacitor across the feedpoint?

200 khz of splatter? Wow.

Bird dummy loads like the ones pictured are all over for sale cheap. They can take a lot more than the nameplate. The 5-600 watt models play nice at 1500 watts average on with HFRF for hours in a climate controlled environment.

An EDZ is 10/8ths wave long. Longer lengths may match easier but the broadside pattern goes away. Best matching depends on if it will be used on other bands. #1 would be a remote adjustable network at the feedpoint with junk cordless screwdriver drives to the variable cap(s) and or...

So this has morphed from a CB antenna thread to a low band vertical thread....
