I had one of these years ago, a yard sale find, it was the AC powered version. The three presets were still set to existing AM stations. Wish I hadn't sold it.

I love this stuff. When I went to tech school tubes were still king, but they started to teach solid state.

one in that size range could work for a 3" cone tweeter/fullrange (say 3fe35 Fatal) that has a rising on-axis response. GregB's Karlsonator has beend sacled all over th place and can offer better bass than scaled won Karlson K15. K15 can sound very good with a good 15" coax 12" work too - its very adept in the upper bass due to the front chamber... There/'s a little "K3.5" plan at Diyaudio - mine have 3fe35 - very good with a helper woofer. I have a 3-way K-stack with "KUE12/pym1298 on the bottom - B&C 8pl21 midrange and Transylvania Power's "The Tube" with compression driver for treble.

Thanks for an interesting video. I will have to see if I can find the schematic on line as finding the magazine will be difficult, particularly because I'm in the UK.

I'm from the tube generation and I love this stuff. BTW, don't worry about obtaining 45 volt and higher batteries. Just snap enough rectangular 9 volt batteries together in series for the voltage you need. It will take up a similar amount of space. The bonus is that you can use alkaline batteries which to my knowledge isn't available in 45 volts and up batteries. Only carbon zinc is available. N1KHB (Naughty One Kissing Hot Babes). And yes, my wife KB1EBF approves.

I grew up in the time when semiconductors were more novelty than anything. In electronics school in the mid sixties we had to build a tube superhet receiver from scratch and make it work properly. The only thing that was premade was a metal plate with holes punched for tube sockets. I wish I still had the one my dad gave me to investigate when I was quite young. Filament and plate batteries were often in need of replacement though. That's exactly what started my interest in electronics both as a hobby and as a career. I've been retired for quite a while and still build things. Still a licensed ham operator and still have my commercial license. I never did actually use my commercial license, but it still served as a recognized credential.

My Gramps had left MANY of all kinds of these mags in the house Mom and Dad bought, when I was 6. These, Popular Mechanics, Science and Mechanics, I can not name all the variables. They just MIGHT be what sparked my interest in electronics. I am 76, first licensed in high school in 65, and spent 6 years in the Navy as an ET. Spent 4 years at NAS Miramar maintaining GCA RADAR and TACAN, all of it TUBE gear, 70-74

The station you couldn’t figure out was WHAS out of Louisville.

Incredible work sir! I’ve got a few digital modern jobs but what you’ve made is beautiful.

Wasn't this posted several years ago?

Mike Peebles passed away in January of 2022. He would've gotten a kick out of your 2-part videos. Thank you for sharing!

73's🎙KD9OAM🎧

I wonder if there is a more modern equivalent of the IS4 used in this design, it would be fun to play with. G6ISF

Those old battery tube radios were neat, almost like solid state! You put together a powerful radio for it's size.

I ended making my own rechargeable inverter pack for 9V and 90v

Does it have a vibrator for B+?

That is a cool radio.

You have some of the coolest radios I have seen on RUclips. I enjoy watching 😊

The aircell is pretty neat and a pretty neat idea and a nice reproduction. If it becomes an issue Lithium cells have a really flat discharge curve.

That's not bad for a self made radio. Its always fun to make your own device . Even better if you use parts from the junk box

I am Assuming that Sub-Miniature vacuum tubes were not a thing yet in the 40's, at least to the general public. I know by the early 60's, they were used in hearing Aids, that was a box that hung around the persons neck, and 1 or 2 earphones. when I was in third grade, there was a girl at my school who had one of these.

Thanks for the video. I went to look at comments to see what else I could learn. I learned people were whining about video quality. I had other questions. I watch on my cell phone so I guess I don't know what they're complaining about. Stay well.

Was this filmed on a Nokia flip phone from 2001? JHC it is crappy quality.

Can you show how you wound the homebrew variable transformer.

Interesting. Nice visual replica work. Ready for the shelf in Ike Godsey's store.

Flip phone with potato cam.

I hope your battery building skills are better than your filming skills...

Please get a smart phone or something. Ditch the potato

Cool stuff. Thanks for the demo.

Video quality is only just acceptable.

What are you doing in my garage/hobby center?!

When was it made?

In the mid 1970's I was 13 years old at the time I embarked on building a Log Splitter because I found the plans in Popular Mechanics. There was a section in the back of the magazine where you could send a money order for plans. When I asked my parents to get me the $6.25 money order was the amount for the plan sheet. Well my folks thought I was insane for one because I would not tell them what I wanted the money order 4. The project, it was supposed to be a surprise for my dad. But my grand father was the mechanical genius of the family he eventually in his last days sick with cancer he still helped me build my Championship winning modified stock car. He got me the money order. There was 2 problems right from the beginning which were the only reasons my grand father went along with the gag. After I got 90% of the steel from neighbors yards and pair of lawn tractor wheels the big problem was I did not yet know how to weld or even cut the steel. The second problem was it was 100 mile round trip to some ancient heavy equipment place to get suitable pump & ram for the project. Suitable also meant affordable. It took over 3 months before we got the pump to get along with the old lawn tractor engine. It took another month to get a gas tank that didn't have a hole in it like the reasons the old lawn tractor was scrapped to begin with and we had success. Then when I asked my grand father when we were getting the new engine for my Go Kart. He said well you're looking at it as he was mixing the can of paint to paint the log splitter. The log splitter I built with my grand father I just sold it about 4 years ago to a neighbor and he is still using that 44 year old machine to this day. I had put a new motor on it before I sold it.

It would seem the entire Batterymaker catalog is being re-uploaded as Batterymaker Mark II.

Muy bueno.👍👌

How did you do the battery replacement? Pics anywhere? Did you stack batteries or use an inverter?

Superhet?

Did you upgrade your HVAC system?🤔

😁

It's smilin', so it must be happy!😀

Are these recycled videos? 2009 Beemers?🤔

I prefer American stations.

Battery maker mark 2. Your RUclips videos are awesome my friend 📹
