Really nice. Good neat job dude. I really enjoyed this. Im trying to learn how to work on mine. You are the first person ive seen that show start to finish. I actually think I could do this but it would be alot slower. Enjoyed to the max dude.
Hey!! Good to here from you GATEKEEPER! I have watched a tune of your video's and lorded a lot thank you for all the awesome videos!! Yep you guessed it Bluegrass!
@@radioactiveamps3961 I see you have quit the videos to bad. I really wanted to talk to you. Wish you the best man I know and understand. Just dang I didn't get a chance to say hello and Talk to you.
Can you set up a video on how to build the ferrite core windings for this Amp ? You are very intricate in your build of this Amp. Your the 1st to show almost every detail. Thanks
First of all, I watch all your build videos. Second, I want to learn more about building these amps. Could you do a more granular amp building video series? Right from the basics like parts used, why you use the parts you do, how to build the keying relay etc etc. From start to finish. With close ups of some of the finer details. I would really appreciate it! Keep up the good work. 73's
That's a great idea. I have been messing with these things for years, and I would really like to learn more about the different classes AB, C etc. Everyone I have asked can't or won't explain it. It's almost like it's a secret or something.
@@kenneth6731 c class is zero biased, good only for AM and FM, not for SSB. SSB is better with A or B or AB bias, make the pills switch on with about 0.65 volt, makes the modulation very clear to understand at the other side of the QSO.
What mix are the transformer ferrites? 43, 61, 67? How many turns of what size wire on the input and output transformers? Awesome building video, I subscribed, I'll stay tuned on your channel. Thanks, Phil in Panama City, FL
I really like the parts layout and the neatness of your builds. If I wanted to build one like this and Add Biasing so I could run AM and SSB how would I do that?. I know I would need to get a stable .6vdc approximately to the base of the transistors fed through wire wound on ferrites. How would I do this and is there a schematic for this amp? Thanks very much, Phil
Those box's are clear coated i saw you buff so239 location however you have the ground tab on the 239 but not soldered to the board. That is a must do. Don't forget.
@@radioactiveamps3961 That's fine we all owe you a cup of coffee anyways, for slowing your builds down and fighting that camera for us. We really do appreciate your work. I like the way you take however much time needed to make it as perfect as can be. I'm a little OCD I won't send my new 2995 to get tuned up because I'm afraid they will scratch it or knock paint on the screws off lol I put a piece of cloth between my screws and screw drivers lol I sent the first one back because it was scratched on top. 700.00 for a new radio shouldn't be scratched right ? lol thanks buddy for everything.
The "Board & Sink" are made by ICA Manufacturing and others. The transistor holes are punched out by the manufacturer. You can order them with as many transistor holes as you need.
Can I ask a favor can you do a list of everything you got okay I appreciate it because I like to try this build one myself and Alyssa things all right thank you I hope you can do this
Yep it will bend them if it is not spread on evenly. Thinner the layer the better it acts and a sink heat away from the device. If it the metallic kind be careful not to get it on any surfaces where it can short out the circuits as well. That's the way I do mine as well, I step torque the transistors in place to spread the thermal compound evenly. About 10-15 inch pounds is more than enough. What transistors are you suing in this build, Hg 2879s? I would mount the transformers on there and then get the + bias rail busbar mounted where I wanted it and then proceed on with the rest of the work. I see there is no resistor and cap with an electrolytic, along with a diode for the SSB so I take it this is for class C only. Too bad. I run SSB alot so I would need and on off switch for that as well. With the electrolytic for the relay delay as well. I do not understand why you don't go under the output transformers with the B+ power to the transistors. Like BBI does, makes for a cleaner looking job to me, if you go underneath with the power supply circuit.
I see that your splitter coil has a 100 (I think) ohm resistor attached to it. On some 4 pill amps I notice that there is no resistor on the splitter coil on what looks otherwise about like the same circuit as your amp with the same board from ICA I suppose. So, was that a mistake on their part or what?
You technically do not need one on the input. That resistor is there ONLY to let you know when there is an enbalance. This will show up on the output first because the load is great during a mismatch. So you'll see some use them on the input....some not. Really isn't an important component for that location.
Do you sell kits and instructions for these 4 pill builds ? Also where can a person find actual literature to learn these type of amplifier builds? Will wait for your response, Thanks
@@wilipno Your full of crap! Getting your licensee does not open up any doors to learning. The ARRL's last Amp Builds Book was what 1979 with designs and components that are out of date and no how do! You had to already have the skills and knowledge to follow the schematic and written description of the circuit!
Congratulations! You just built an irresponsible splatter-box. I guess you don't care about anybody but yourself. Where is your harmonic filter for the output? Do you not care about who you interfere with?
Good day rambling man. Nice video. Curious looking solder. If I am not mistaken it is the first time I have seen solder that looks like it has stripes or twirls. To the best of my knowledge I went to the American solder website and i did not see that solder in their catalogue. Do you know if it available from American solder? I am typing from across the peace bridge from Buffalo NY stranded in Fort Erie Canada!😊✖
Can't he a word he is saying and pretty worthless video if you don't start by showing a circuit diagram, really have no idea what you have built other than it is a RF amp
Bro stop chewing up your finger nails and get some medication to get rid of that fungus that's on your fingers. Looks so sickening that I couldn't watch the video...smh
Nice clean build I'm on disability I enjoy CB radios I will get me a box like this some day right now I just run barefoot 73s god bless.
Thanks for sharing the knowledge friend, is very interesting and fun to build such a very delicate piece. TX 77 waiving from the desert, click click.

That would be awesome. He could even make a playlist of videos with the steps involved broken down into segments. Get way more views!
Would be great if he broke the build in stages and with a parts breakdown.👍

Good vid mate
Thanks for sharing Ramblinman! Hey this thing doesn't do SSB does it?
Do you have a parts list of whats needed and where to get them from? I really want to get into this
Parts list would be nice
Can these be bought as a kit or you have to order every part of it individually?
What mix are the transformer ferrites? 43, 61, 67? How many turns of what size wire on the input and output transformers? Awesome building video, I subscribed, I'll stay tuned on your channel. Thanks, Phil in Panama City, FL
I use all type 61 ferrite, three turns of 16 Gauge Teflon Wire on the input and the output transformers .
i would buy one his amps he does good work. do u have a wed site u sell them on or do u sell on ebay?
I really like the parts layout and the neatness of your builds. If I wanted to build one like this and Add Biasing so I could run AM and SSB

Still need a bias schematic? what device are you using?
Thank you 💯
this very helpful 👏 can you do a little more detail on the peramp and relay circuit?
1.05K subscribers plus me. do you have videos on how to do all the stuff you already had premade? or a parts list? this is interesting
Sir where do I get all the parts? do you supply this as a kit?
Those box's are clear coated i saw you buff so239 location however you have the ground tab on the 239 but not soldered to the board. That is a must do. Don't forget.
Can't wait for tune up.
Did you solder the ground lugs on the so239s
Yes I spun them around and solder them down to the board . Good eye!
Sorry no tune up video for this one.

Those transistors don´t have bias on the base? or that amplifier is only for FM operation.

I'd love to have a parts list for this four pill amplifier I'd like to build one myself but not sure what parts to buy
Thanks for the sharing mate. One question how do we do the bias on SSB? I am new on this hobby
Apply .65 v on the base of the transistor for AB bias.
Yep it will bend them if it is not spread on evenly. Thinner the layer the better it acts and a sink heat away from the device.

Hello ramblin Man how can I contact you about purchasing one of your apps
I just got an 8 pill biased for ssb. Can I talk am and leave my ssb switch on?
Do you, or would you sell these kits, and we can put them together ourselves with an instruction manual?
Mr RADIOACTIVE would u be willing to get ma a parts list i would be willing to pay for your time..
Where can we buy this kit ?
Another question...how’d you separate the solder on the pill 💊 strips between the transformers?
Before I put solder on the pill strips I use a hack saw blade to make the cuts. Cut just enough to take the coper off. Then solder the strip.
RADIOACTIVE AMPS! Gotcha👍 I kinda figured what to do afterwards. Thanks for replying🤙
Hey bud howd you tune the amp after it was done?
Where to buy the kit ?
Can you send me photos parts list of 4-pill i wanna learn how build one theses for my cobra 139.
Where can i buy one
where do you buy the copper board?

Go to ARRL.org and get an Amateur Radio license. Then you can not only learn how to do this but can do it legally!
@@wilipno Nothing illegal about building an amplifier.
@@shishkabobmiller2693 if you build them for Citizens Band they are! That's why I mentioned getting an amateur radio license.

What’s the value of the 2 capacitors on top of the input transformers?
270pf

Sorry bud I told you wrong Judy Carol has 330pf over the input transformers. It's Lillie that has the 270pf Sorry
RADIOACTIVE AMPS! No problem sir. Starting a 4 pill build so was inquiring about parts/values. Your builds came out nice🤙
RADIOACTIVE AMPS! Check your messenger, asked you a question on there also.
Will you sail a man that kid your fixing the build and let him build itself
Wish you built to sell
What happened to the channel did he die
Hello are you okay
$$
I noticed all of your builds have female names what's up with that
No quiero amplicadores con toroides tienen armónicos no tiene filtro
Pay attention you tech nine technology can do this and you shut his channel down then why is this channel still running
Boooo :(
