Hello .. I was a CB/11 meter fanatic back in the 70's, 80's and very early 90's. Had so much fun. Would get on AM in the evenings and SSB in the afternoons. Had a 2 element quad on top of an 88 foot (tilt over) pipe tower. A 5/8 wave vertical for a backup. It was amazing. I run a President Madison into a Boomerang Amp. The tube amp just plugged into the mains. I had few smaller amps, but the boomer was by far the best. If I remember correctly it had a lighted rocker on/off switch and 5 toggle switches on the front, a large meter and a tune and load control. You couldn't miss the name .. Boomerang in big redish-orange letters. It had a pre-amp / boost receive that worked really well. It was one of the 5 toggle switches. I can't remember exactly what they all did now. Think - ssb/am | boost receive | hi/lo | by pass / stand by maybe? Been close to 40 years ago now. I sold the thing around 2004 and the guy burned her up .. running into a broken antenna. Sad .. I need a new amp. Anyone else have a boomerang?
Always top notch video teaching and learning the best things to do with your equipment. Very educational to people who want to learn in the people just getting into it thanks again for everything you do for the hobby.
This video right here is exactly why i am a patreon supporter of BBI. I mean when the heck ever is an old mud duck radio guy like me who probably will never break the 300 watt barrier in my entire life....where would i ever get to play with a friggin 10 kilowatt transmitter? Its as if the mad proffesor lets me into his labratory and the entire time he is explaning every small detail about whats going on with the latest experiment. Its really a the funnest time of a day when the newest BBI video comes out. Thanks a bunch BBI for all the teaching you do for us all. You will always have me on your patreon list. The DragN'Fly in Tennessee said that.
BBI...I have been trolling your channel again for a few weeks now. Used to watch back several years ago, glad to be back. What an amazing deal some lucky person got there. That to me is the gold standard of amp...love the old glass stuff. Not that you need to hear this, but that was a very honorable amount of work you did to help out the family with that project. Seems like just the kind of dude you are. Look forward to getting to work with you myself someday. Headed off to the Patreon now bud...73's
Love the glow in the dark equipment, I am surprised that it doesn’t have a dead man switch like old broadcast transmitters . Enjoyed your video and all the details.👍. KC5HHB Delmar
Excellent straight board presentation on this amplifier.. Well demonstrated by you of course BBI.. It would be a dream down that.. and the price you put on it is just extremely fair and unbelievable., for this grade of equipment.. I enjoy your videos, I'm into electronics have been for many years. Myself I have a pride DX300 that was left to me by a friend that passed. It has problems on the capacitor boards. And I intend to purchase new boards and get it online it's got to steel tube in it.. can't wait to get it up and running and memory of my beloved friend fast Eddie... Thank you for the great presentation.. keep rocking and stay cool. And by all means keep up the great work.. Sincerely; C Kirkland... Kansas City Missouri....
Man I love the old school shit where it shows thought into the item, craftsmanship,it is just hard to find backup parts. I miss tinkering .my stroke took my tinkering fixing odd and ends away from me. That amp is standard to operate. That was a pretty and sexy peace equipment. Love it❤. But my radio days are mostly over after my stroke.
Your asking price is more than fair! You did a really good job presenting this amp. As to UA-cam, UA-cam treats all of their content up-loaders like garbage... Welcome to UA-cam...
Your big Amp looks a lot like an older RF laser driver I got to play with. Pumped 6kW of 27MHz RF through the co2 lasing tube, with a 2KW beam output about the diameter of a quarter.
bad design, filament leads coping up on top RF deck, biggest no-no in building 101. always below deck with chokes and caps if a fault occurs. otherwise RF will leak back through it all, probably even go into oscillations and nuke itself on the wrong band or harmonics. poof.
I like this video as well. We radio amateurs are a the minority in today society. I like to fiddle with old radio/amp stuff. I do not own such beautiful old RF amp, but a homebrew audio amp , 2x 1500W with 4 of the GU81 valves. (2 monoaural) amps It run with 2700V at the plates. I had a lot of fun while build it. My transmitter is an relativ modern Transistor version made by german company named HAGENUK. It drive impressive 1500W into the antenna. Not that spectaculary beast like an valve amp of the same output.:(
Excellent price!! Would have loved to have picked this up.... Maybe I should bring you my single 4-1000 box, and see if you can bring it back to life. 🤔
Man... 3,500 is a freaking STEAL for this sweet talking machine. If I still played on the band, I'd snatch this up in a heartbeat. Whoever fires down with this is gonna get their name called...no question!
I wish tubes didn’t scare me so much. I love how effortlessly it makes power with low drive. Just cruising. Probably never gonna have another base station either.
that a super amp. looks like all grids ground. that another way to run them. only thing i would add is some safety interlock switches ground HV remove 240V in. and a voltmeter for the filament. it would be ok to back down filament voltage before turning off filament supply. how we do big broadcast tubes. a cabinet ground is a must on any amp like that. 73's
BBI, would love to see ya build a box with a Eimac 8974/X-2159 tetrode... - Thoughts? - All Ribbing asside, mega appreciate your content, as a former broadcast engineer working on TH347 and 4cx10000D based transmitters, its fun seeing what can be done when you think/work outside the box.
WoW..Thats A Deal..IMHO..i have ben into radios sense i was 8-9yo /35+ - Years & i gota say that is sweet.. i had 2 grand ish into a old 4 tube 3-500z peace that looked like well you know..lol. i had a L4B Drake that i rebuilt & just drove it with my Pride dx 300 also All the Upgrades & Mods stock tube though that i tickled it with mostly ! Man o man the fun i could have had with this haha..
Pretty sure those diodes are X-ray machine/MRI surplus of some kind. I bought a few of them a long long time ago and that's what the Ebay guy said. In an era of LDMOS amps this amp is proof that there's still cool tube amps out there. At $3500 it's a bargain, but I think you'd have a guy that comes to you asking for it not the other way around. On a setup like that, one thing I would like to have is a cabinet safety interlock. That is a heck of a lot of voltage to play around with. You likely wouldn't get a second shot if that thing gave you a hit.
I dont know how I missed this when it came out. Must have been out on the trail. I'm a tube guy. Yeah they make some really good solid state legal limit plus amps but in my head they will never be as robust or sound as good as my tube amps. One ceramic tubes and one is glass. Not much difference in operation for me but the glass tubes just seem to have more personality.
Mr. BBI, I operate a small technology company refurbishing used Electron microscopes and X-ray microscopes up to 225KV DC. I agree with you that doing anything to try to improve a tube's vacuum is a waste of time. The only way to do that would be to put it back on a UHV pumping system then, resealing it. A Getter is the internal silvery coating of pure titanium that is seen inside many tubes. Titanium is used because it has a high affinity for Oxygen and other halogen (highly ionically reactive) gases that may have been left inside, even after high temperature baking while being pumped for days using an ionization Ultra High Vacuum pump. If a tube becomes gassy it's because it has a vacuum leak, probably as a result of rough handling that caused a micro crack at one of its' electrical feedthroughs. There's nothing that can be done to improve that. Only if you vent the tube, disassemble it to remove dielectric oxide coatings on all the electrodes, replace the base to replace the leaking feedthroughs, then repump it for several days while using an induction furnace to rebake it. You'd have installed a new coil with Ti powder that you would flash in an RF coil to create a new getter coating. It's cheaper to just replace the tube at only $550 each today. Vacuum, electron transmitting tubes are technological wonders. Are there any Metal-Ceramic tubes that'll make 10KW PEP selling at just $1100 new? I don't think so. How about LDMOS? No. Still about the lowest cost way to go is what you have right there.
I just acquired 1/2 of that box from a silent key. It's been in a basement for over 12 years so I'm going super slow mo and checking everything. It appears to have a half wave rectifier. Why?? Can I build a full wave and stick it in??
Sorry BBI not my intention to offend in any way testing into a dummy load always shows zero reflect and flat SWR what I should have said is Does SWR go up when testing into antennas? because Im getting to high SWR with amp inline, barefoot its low seems like the amp and meter inline is driving up my SWR who knows what it would be if I put a small driver inline? what am I doing wrong? Your a great teacher BBI.
Oh man, the guitar amp idea... dude, dude.... This has been my basic question all along, only I didn't realize it till just now. Then 2 minutes ago I was yanked out of my stupor by your comments on the subject. This must be done. What would it take? I don't think I have a clue. But I know you do. I can't bias a transistor, or build a proper amp... But I can play the piss out of a guitar. And I can dream. Peace.
man thats a nice box..id love to get rid of the 3 z box for this. Them needle chasers hahah 😂😂😂 can we get ol smokestack to build another haha .. It is a bad box.. 4 pill or less and be done.
U best used whats paid off that's what I have 2 3.500 z in ssb 220 had it sense 2011 still has same tubes just updated wiring and caps there pretty bullet proof
filament leads that come up around on-top of an RF deck? NO! BAD! unless it's fully RF and HV isolated compartment. the only thing at RF deck level should be things that are handling the RF directly. that should really have an RF screened enclosure behind the door. yeah, I get it cost over safety, safety third etc. we've all done it on home brew and half-butt projects.

@@BoxBuilderIdahoIt was meant as a joke, your going to need some gas money for a cross country trip...how much would a cross half the planet trip set you back...
You know I have this henry 2kd classic sitting here with your name on it luke,, lol .. I want to trade it for some sweep tube equipment, I need a tube tester and a variac...
This looks like someone decided to build a broadcast station level system for “home” use.
BBI, you're a class act! Appreciate you stepping up for the family to help and protect them...
He neeeeds to grow up socially. Its like that guy who pretends to be AvE but isnt fucking funny and all he has to do is relax and be clever.
YES BBI is a GREAT teacher and he's pretty damn cool also.
