Re: Fl2100z swr
What are you loading up to? An antenna or a dummy load. Do you have an antenna tuner? Lou WA5LOU Lou WA5LOU

Fl2100z swr
My fl2100z seems to work perfectly but for one curious thing. Tune the rig to the antenna using a manual tuner (palstar) with amp either off or on v low power.? See see of c1:1 Tune up amp normally

Re: Array solution BPF-6 with an Dentron amp
Far Circuits has a bare board to build a tuned input for the GLA-1000, it might also be adaptable to the Clipperton-L. You supply the parts of course. http://www.farcircuits.net/ 73,Chuck N0NC

Hi Dave, Glad you mentioned about the KVI type russian doorknobs as supplies are still around and I did get a few through the post recently. Also K15-5 type 6.3kV ceramics (proof tested to 9kV so ufb

Re: Plate blocking caps YC156
Having looked at the Draloric data sheet for the 2500pf, R85, PE 200, 14kvp Ceramic Disc Capacitor, it looks like it is rated at 60 amps RMS Tracey G5VU

Re: Plate blocking caps YC156
I think one of those should do the trick, Tracey.??They're a bit physically big, so I'm not sure what they'd do to stray capacitances for tuning on 10m but quite a few builders use

Plate blocking caps YC156
A number of high voltage/current rating ceramic capacitors have just come up on eBay in the UK. It looks like they have come out of some kind of RF heating or medical equipment. I'd be grateful for

Re: AL-811Question
I think somewhere in my ¡°paper¡± archives I have either a GE or RCA bulletins. I thought that one of them showed how to make a home-brew test jig that would adequately test emissions of

Re: AL-811Question
A tube tester uses low voltage to "test" emission which is far from what the tube does at HV and with RF. Even my fairly high end Hickok 752A is only good to give a quick and basic answer ....if a

Re: AL-811Question
Yes you can.but dont mix brands. Stick to Chinese, USA, Russia, etc Also do not run at more than 450W out for longevity on the 3 tube amp (600W with the 811H) with import tubes as they are not true

You can if they are good. Have you checked them on a good tester. My preference is to buy all three with matching attributes. But, that is not necessary. You ca replace the one that is bad. But, be

AL-811Question
I am repairing an AL-811 that was blowing fuses. I found one of the 811 tubes had a short between the filament and plate. My question is can I buy an 811A tube and run it with the two existing 811

With some older analog VOM's having a 6 KV socket Id say the probe wire is good to at least 10 KV, Ive seen regular RG8/213 used to over 6KV in commercial installations to run HV around.but I wouldnt
