Well Mike, I see you have two choices on which way to go with the Streampunk Regen radio: 1-leave it as it is as a museum artifact as an example of a poor regen design from the 1920's. 2-make the circuit modifications to improve the performance, without changing its outside appearance. Although some of purest would baulk at any changes to the appearances of the internals. For me, I would want to improve the regen radio, to make it work better. That would be more enjoyable!
Hey Mike, great video and progress. Here is what I suggest…..This receiver was a work in progress for the fellow back in the day. He was experimenting and learning as he went. i would put a copy of the schematic as you found it and then repair/enhance the design in honor of the original owner stating that you picked up the experiment where they left off. I think that still respects the original builder and lends to what we amateurs do to advance the art. 73….Larry W4PJP
Man ! Your videos take me back to my grade school days of Knight-Kit regen ($24.95 in 1964 if I remember right: a lot of money for a fifth-grader). Keep em coming, Mike! 73 de ae3m :)
With old home/kit built stuff like this I think its OK to correct what we can only assume were mistakes in design or assembly, e.g. mirroring the filament circuit. Just make it look right (at least at a glance) and don't redesign the thing into something substantially different, there lies madness and hackery.
Hi Mike, another good and informative video, thanks! I love the period title graphics too. I would like to see you develop/modify the circuit to get the best from it and show just how well it is capable of performing. please. Best 73, Ace G0ACE
At 10:30,.....The detector Already has the Plate B+ regen Control Potentiometer to adjust the regen Activity.....The "A" Battery was probably 3 1.5 volt dry batteries wired in Series for 4.5 vdc when fresh New.... The 20 ohm Wire wound Rheostat was most likely used at near Maximum resistance with New batteries & gradually adjusted Lower as the "A" fillament batteries Aged.....Running the Fillaments at Lowest regen Operating Voltage would Significantly extend "A" batteries Useful life...
I thought this was supposed to be toroid free! I want my money back. We don't need no stinkin' toroids! Great job on this series! I love to see you work through all of the problems and not be afraid to take on new challenges. Thanks a lot for posting and keep going with this project. Thanks for posting and 73's!
👍Thanks for video Mike. It's the usual restoration dilema - different folks have different views. For this, my take would be minimal change to make it work to an acceptable level. As someone suggested, you could leave a note of the orginal circuit and the modified circuit inside the set (plus any original parts). This way, any future technical archaeologist may restore it to original condition.
Speaking of the R29 Regenerative Receiver; Would there be any changes required to use type 27 tubes? This is keeping the Bruce Kelly QSO Party in Mind.
Great Series! I have been looking at your R29 Regenerative Receiver on your Facebook page. I see the Throttle Capacitor C4 on the R29. Would changing the Scotty Regenerative C4 to a variable capacitor improve ease of operation?
It’s a artifact that needs improving, I’m sure the original designer if they were still alive today . Would love to see you, improve their design and make it even better.
Just fix obvious wiring mistakes like the rheostat, and turn the regen control adj around so it's not irritating to use.

Great Information and Video !
Make it work better and you’ll actually enjoy and use it!

That can not stand! Anathema!
Mike,congrats on getting it to at least work,,keep going to improve it ,thanks ,73, Jerry
Thanks 👍
iam sure the next vid is done already lol... but i would say fix the reg on the ground. at least lil better then . 73 from wvo.
Definitely not steampunk any more as it's now functional.
Always so cool to see something so old come to life.
I vote for driving on Mike! 73 - Dino KLØS

It does have significant flaws that limit basic operation.
Thank goodness this isn't a short. I was losing all hope
Speaking of the R29 Regenerative Receiver; Would there be any changes required to use type 27 tubes? This is keeping the Bruce Kelly QSO Party in Mind.
27 or 01A types would work with only filament changes.

There are several things to go over. Looks like another video is needed.
I think you need a/c ground paths on both tube heaters .
Would adding a 100 nF cap between the tubes & 0V help ?
Yes. The tubes will couple nicely through the fils promoting feedback as is. Lots of issues.
Press on Mike, you're so close...
👍Thank you sir.
It’s a artifact that needs improving,
I’m sure the original designer if they were still alive today .
Would love to see you, improve their design and make it even better.
