Did not say they overheated, this is just a precaution I mentioned as some might not be aware to keep the vents in the clear and the fan area clean.

Yes, that is correct.

I just bought 4 boards from him, they shipped Monday 08/03/2026. I should be getting them any day now. It only took a couple weeks to ship but, I told him NOT TO HURRY as these are just for a future repair or build. I try to remember to post pictures of them when they get here.

If it interests anyone go look at ham amps with the 2sc2879 and the cb amps with 2sc2879 video watt tests. For some reason when I build one I get pretty much what the data sheet says when I drive each transistor with 8-10 watts, good thermal tracked biasing, and along with a good LPF. Sure I can...

He is selling those boards now. I bought four of them due to no time to make the boards from scratch myself. Each board serves 2 transistors. He uses the TIP31 setup. I dont know of any fulltime builders using that bias setup yet, the ones that do bias is just the diode/cap/resistor deal as far...

I like to use the TIP31 setup.

OK, thats the better options, the other info you sent was just class C. I personally would skip the C transistor upgrade, I find the regular HG's to be a bit sturdier. Also, dont drive it hard on SSB as the HG's dont like that. Stick around 6-8 watts PEP per transistor, so a 4 pill would only...

They all say Class C in your post. Non of those will be clean for SSB.

Well, there is nothing wrong with thinking about antenna building. I build all my own antennas, wire antennas I should say. Working on a 80-10 meter 1/2 square build right now. It will be center fed with 600 ohm ladder line and replace my 100' doublet and use its 3/16 Dacron rope supports at 50'...

I have not put any math to it yet but just thinking about it there is no aperture to get good receive and I bet it would have huge deep nulls and peaks but perhaps more vertical and I dont think the swr would have much bandwidth if you can match it. Then the opposing currents would not be...

Are you doing this for space constrictions?

I use similar bins as well. I have a cabinet with bins for 2879 and similar amps with all the repair parts in them and labeled. I also have a cabinet for the Ameritron tube amp parts as well as a bin for their solid state amps. Another cabinet for all the popular range of caps and resistors for...

Reminds me of the old Astro plane Beam, maybe its Astro Beam??

Loved that commercial, thanks for sharing. Sometimes I catch Anthony and Luke on the bowl. A couple months ago I got my named by Luke with my whole 100W out of my quad6 and Imax, I guess Anthony could not hear me that day. I guess I had awesome conditions that day from NE Texas, never even...

I understand the rules and wish to enter into the drawing.
