The Scotty Regen really needed to be disassembled and parts removed inspected and cleaned up. Some parts had to be replaced. Re-wiring with period correct Double Cotton Covered wire.

Great project! I also have an old early 20's regen that shows it's lineage probably back to a single tube build. I can see where someone grew an audio stage and crammed in an "amplifying transformer". I had to "fix" the ACME transformer because the bee's wax had some impurities and corroded the fine frog hair wire. ...probably will break again somewhere. It uses a UV200 for regen and a UV201 for audio off a single B+. It also has a variometer tickler arrangement, and no antenna tuning, and linear variable capacitor that covers 500-1500 kc in one swoop. It is DSC wired, although the "old" regen part is wired with a funky "square" naked bus wire. I have never seen this before! So, even though it could benefit from a rebuild, I chose to leave it for techno-archaeological interest. 73 ES GB Sam W3IHM

I have a breadboard 3 step 01A amplifier with that same square bare buss wire that is looking for a restoration video.

I can see why you had to disassemble the SteamPunk radio, in your hands this regen radio will work better than it did in the 1920's.

Back to the beginnings of the history of electronics. I like it. I recall opening my Arborphone 27 receiver, looking at the bottom of the chassis and thinking it had been stripped. But it hadn't. There simply wasn't anything to it.

Tubes have a lot of gain with simple transformer coupling. Trying to do it with less costly parts usually drives up complexity.

“Push-back” wire, very cool, first time I have heard of it; I love your channel, thanks for the great videos.

Push-back wire is for those of us who are to young for Strippers!?!

Thanks again Mike..great content as usual..good, slow methodical camera work that truly helps a novice (or professional) understand what you are doing. All this old, institutional, classic radio engineering has been lost and very little appreciated today. Keep up the great work!

Final video goes up Wed. Thanks for watching this series.

More excellent content, Mike - thanks. At 7:35 try putting your hand close behind the grid leak, palm facing the camera, so the lens will autofocus and show the component's innards more clearly.

Yes that old Cannon was not happy, and lighting helps but it does not cure everything!

I need to build one someday, but I have too many projects already and just getting caught up on this series.

Great video! I have never seen such old components! After one hundred years they are still holding toghetter. I think Bakelite has to labeled a "stable material". Modern plastic will not last one hundred years...

Celluloid was old news by this time and and Bakelite (an early low-cost, durable plastic) was in full production and the world’s most abundant plastic, polyethylene, came by 1933.

I recently picked up a homebrew crystal radio that is in a similar state to this one. It was made from an old AK20 compact, that was seriously hacked (and hacksawed).

Hi Mike! I m currently assembling regen for my blacksmith shop

Nice! Great to have an old time technology radio in the shop!

Great job Mike... Looks fantastic... looking forward to hearing it in due course...

Oh it's playing. The tube base plug in coils with the internally hidden tickler winding are fascinating, and I will build one from scratch.

I'd be tempted to set this up for Field Day, and run it off solar panels.

Fun fact: early tantalum capacitors had electrolytes so corrosive that they needed solid silver cans. Worth a bit if you can find them!

@MIKROWAVE1 6 ай бұрын

It amazes me how fast the US, UK, Germany and France created a whole electronics parts industry in such a short time period. I think AT&T came up with the solid electrolyte versions later.

Looks great! When are you going to design the Shih Tzu regen? Interesting history on the tantalum capacitors. I thought they were a relatively new invention. Cool looking cloth wire. Thanks and take care!
