Amazing boxes, I played with CBS ever since I was 12 I'm 65 now up here in the hills of Kentucky always wanted a box like that blow my mind, do you have a way to find a price list on some of your products, just ran across your video this morning God bless keep up the good work, PS I run an old phantom I think it's a 12 tube I run it about 1200 w I think my tubes are getting weak I've had it for 28 years never changed but maybe three tubes in it I'm sure it's getting time 😝
I don't think I've ever seen anyone turn the high Voltage on before the heater. I wouldn't think that was a good idea. Another thing. If you look at the schematic of just about any tube RF amplifier ever built you will see that the very last thing in the tank circuit headed toward the output coax connector Relay is an Inductor or rf choke to ground. Why the hell is that there? Won't it short things to ground? Well yes and no. If you have a blocking capacitor fail shorted then it's that choke that shorts the dc voltage to ground. AC as in RF doesn't see that RF choke to ground but DC does. If you don't have that choke there and the blocking capacitor fails shorted you are going to see all of that Plate Voltage at the antenna connector where you are plugging coax in and out. Plenty of homemade amps have been built without them but its very very dangerous to be absent from the circuit. Here is a SB220 Schematic. The RF Choke I'm talking about is in the bottom right of the schematic slightly above the area marked meter switch on the schematic. It's almost unnoticeable but highly important. The blocking capacitor is up at the top of the schematic near and to the left of the tune capacitor (C1). This capacitor passes AC/RF but keeps the high voltage DC off the tank circuit. www.worldwidedx.com/threads/heathkit-sb-220-schematic.259853/
I don’t build tube amps. For most part I think filaments stayed on. Far as I know it had a choke and blocking cap. Local ham op built this. Y’all can have at the HV Amps. I don’t mess with it none anymore. Thanks
I've been a ham since 1981 (cbed before that) and I have one of those tubes built from an old Henry Generator Cabinet. Good tube although I never ran mine 1/3 as hard as you are running that one. It will get after it on AM though but most of my time is spent on ssb. Using the 5000a Flex I think I would set the carrier at 375 watts on AM it it would modulate to 1500 or so pretty easily. Lots and lots of headroom. Wasn't trying to be a smart ass just worried about your safety. @@DonkeyStomperProducts
Your fine this amp has been ran several years now still going. I know the owner still has it. He does really good in DX on 28. All good this was done when I started building transistor amps by a ham op years ago. Its always been good amp. Yes HV is on edge of what the tube can handle. I don't own a HV Amp period these days. Thanks all good.@@n5ifi
How do I get in touch with you? Oh and some of those boxes that you have around there all day old going out to someone I really like to have something plug in the wall 2000 to 3000 W not very much to ask for not coming from you, but do you have anything that’s ready 511 N. East corner of New Jersey. Happy 2023 I need something so I can take down to one of my houses in Myrtle Beach. And set up there with my MACO 6c

Very cool!
Lets see more of the 64 pill
Will post more as we work on it. Where not building it only all time. Working on it on off.
@DonkeyStomperProducts I hear ya. I'm in the same boat really. But when you go to work on it show us a little. Some of us like that kind of thing
That thing is a heater Beavis 💪🇺🇸
She talks he is in middle of moving.. Just listen for 672 Six Pak TN!
I want a 110 box that does about 2500watts . Is that possible? And how much would that cost?
yes check on my fb page! facebook.com/DonkeyStomperProducts
Dam wish I had the money Fer that. I think it blow my Antron 99 antenna to dust! Lol. EXCELLENT EXCELLENT VIDEO!
Thanks!
Who are the top HV builders these days and do you have there contact info?
No don't have names numbers, John Boy TN, Wizard Built, Blue Ghost, Some that come to mind. Might ask D-Rail he is in to that sort stuff.

Beuatiful my friend.. how about ten bucks have we got a deal lol..
awesome pal you take care and stay safe have a great day.
Thanks!
Wow man that’s nice
Thanks!
Nice !
Thanks!

pretty sure you want filament first.
Yup
