21. Re: [Amps] HV Connectors - Millen? (score: 1)

I would worry that if I were SK and a less experienced ham played with it to help the estate? Antenna connectors look harmless, but having B+ there could kill a nice guy. I do agree with the Millen i

Could it be the antenna heating up and causing it to click off-line? I don't know if the amp has any VSWR or Over Current Protection but I have had antennas heat up, catch on fire or melt from time t

They sure do look cool though! It runs out of steam above 20M and up plus it really should have some forced air when pushing at ICAS ratings, seal ratings are only 145*C. Its a fine AM tube but rathe

I think the right answer may be to MARK "HIGH VOLTAGE" Even when unplugged or some such. One of the "fit and proper" connectors for HV got me once and I was very lucky. I had a rack-mount Henry 2002

Now what for owners of old amps. Will it be like the Svetlana 4cx1600 or will the factory have a retrofit. I've been pondering the purchase of a new amp. The AL-1200 looks like a good fit to my requi

What about the guys who are only allowed 400 Watts. Should we back ours down to make everything equal? Does that make running 1.5 unfair? What if we win? Was it stolen from the guy with a 400w limit?

I wonder how you would account for propagation. The ionosphere is pretty nebulous and it is normal for ebb and flow of 10db during a single transmission. When it is not in that state, and there is st
