Hi, Mike After seeing your post, I googled 833-C and saw your picture on one of the sites! In the "old days" they were 833A and didn't have the big graphite plates! :-)
Have fun! BTW - I have a 3-500Z amp that evolved much the same as yours! I don't have a complete schematic either. It started out in life as a GG 4-400A 160 amp that was built by N4JJ. Over the years, I added bandswitching and converted to 3-500Z -same socket and wiring and I wound a ferrite binocular input matching transformer that works fine 160-10m! Nice to see someone doing it the way we did in the "old days"! :-) Regards, Charlie, K4OTV -----Original Message----- From: Topband [mailto:[email protected]] On Behalf Of Mike Waters Sent: Sunday, May 12, 2013 10:45 PM To: topband Subject: Re: Topband: 160 and 80 meter QRN prediction Well, mine's not much to look at. I sort of designed it as I was building it, using junk parts that I had on hand. And there's things I should have done differently. A short explanation is at http://www.w0btu.com/833C_linear_amplifier.html . There's no complete schematic. It's not completed yet. I'm just having fun using it as is right now. And we're certainly looking forward to the 160 DX season! http://www.w0btu.com/files/misc/833C_linear_amplifier/?C=M;O=D has other photos from different stages of building it. 73, Mike www.w0btu.com On Sun, May 12, 2013 at 9:21 PM, Charlie Cunningham < [email protected]> wrote: > Wow!!
