221. Re: [Amps] Chimneys for Russian tubes (score: 1)

Paul, In this case, you could stop the chimney just short of the ring, or make the chimney about 1/8" to1/4" diameter larger than the ring and anode fins. This would allow the air to pass on each sid

Manuel, I seen some on Ebay for sale the other day. They had several different band switches and also several roller inductors. To by a new roller inductor, you might want to try Oren Elliott as I'd

Tom, Good to see your back up and running. I figured I'd mention this because of the request for the GU-84 socket. There's two versions of the GU-84 tube, one slightly longer than the other. The shor

Tom, About three days ago, I seen about those GU-48 tubes at a Russian website. They showed about the different lengths and also there's a ceramic type which supposed to be the same as the glass body

I finally run that website down, and I screwed up when I posted about it. That was a GU-43B, not a GU-84B. I recalled the number being familiar, and see now they are about the same but backwards, 3 s

I'm looking for a good used gaussmeter that will read at least 50 to100 kilogauss. I've looked around on Ebay and most listed are without the probe making them useless. Most times, a new probe, if st

Did anyone ever notice that the MFJ grip dip meter they have now is a direct copy of the old Leader LDM-815? From what I can see, it is right down to the coils it uses. Same meter, same layout, etc.,

Bill, I should have mentioned that was gauss per sq inch. I figure some of the older ones may have measured it this way. Actually, I need one that will measure something like 10-20 kilogauss per sq c

Bruce, I've seen them used with success. The only difference is they're straight and the SK406 chimney folds over top of the tube forming a mouth. It was designed to try and force some air over the t
