if you genuinely believe that then I guess you'll be the next one to get popped for transoceanic aviation QRM. Rob K5UJ _______________________________________________ Amps mailing list Amps@contesti
I used stainless steel hose clamps for the cathode connection on my 160-meter amplifier using a pair of GI-7bT Russian tubes. The heaters were the size of the plate cap on a 6146 so I used a couple
Ask Dr Alex, I was just looking at a photo of a 2X GS-35B amp. Carl KM1H _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/list
You have to see that photo. I thought I trashed it but here it is http://www.cqham.ru/foto/showphoto.php?photo=761&title=-d5-ce-d0-ce-d8-cecf-ce-cc-ce-c3-c0-cb&cat=500 _______________________________
If you grab a GS35b or GS31b and have a close look at the way it is constructed, you'll see that the use of a soldering iron on the heater/cathode connection points will not damage the tube or the se
I didnt say it damaged anything; the amp is operational. It just looks hokey and not anything Id take a photo of. Carl KM1H _______________________________________________ Amps mailing list Amps@cont
Wha? No shield from input to output? Mike KC7NOA _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps
You're right. It was Bill what said it, I fink. Anyway, I have the VE3 sockets and I'll probably use them in preference to anything else if/when I ever use that type of tube. The picture illustrates
Its a good example that you can solder on the heater terminals.... I did..... _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman
REPLY: No ducted cooling? Interesting. 73, Bill W6WRT _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps
REPLY: Also, I firmly believe if you're going to mount the plate choke that close to the anode(s) you should put a shield in between. There is parasitic capacitance between the tube and the choke tha
My turn to kick the ball- comparing the 8877 to a GS35b is like apples vs oranges. The Russian tube has a mu of 13 vs 20 for the 8877. The tradeoff- durability & max QRG rating. Exceed the published
Hi All, I have placed this picture of GS35b PA only to demonstrate how it is easy to build PA with this tube. It can work without socket, in horizontal position as well, with modest air cooling. It i

Good point Alex! I started my amp building career with a super designed, fully protected amp. That amp turned out to be too complicated for a beginner, so I derated my expectations and quickly built
How about the same room with a 4CX3000 running close to tilt? <:-)) I do believe that the YC156 or even the 3CX3000 are much quieter. Yah, some things were really cheaper back then, but back in the m
