Here's my second DIY project...

I made everything at home: PCB, inductor, electronic design mods, frontplate cutting, labelling and design... Just a few euros spent on this project and a lot of fun making it !!!

Looks great.

What does the "Ultra Enhanced" refer to?
Imagine a wet, slightly chilled from its gas release and decompression, with water droplets condensing, sucking surface tension, slowly sliding down the side, capped by a healthy virgin froth on top..

You can find an "enhanced pultec" schematic here on Prodigy. It has 5 frequencies on the BASS and HI CUT section, and 11 in the HI BOOST. Because my rotary switches were 2x6 with no way to stop them in the 5th position, I had 1 frequency in the BASS and HI CUT section so I've got 6 frequencies... And the HI BOOST switch was selectable, but when I bought it there wasn't the stop ring so I decided to had another frequency in this section too !!!

So there's :
LOW BOOST/CUT : 20 - 30 - 60 - 90 - 120 - 250
HI BOOST : 500- 1k - 1k5 - 2k - 3k - 4k - 5k - 8k - 10k - 12k - 14k - 16k
HI CUT : 2k - 4k - 8k - 12k - 16k - 20k

I used RM10 ferrites from EPCOS
Here's my DIY winding machine :



And here's some ins photos... This is not really perfect, but it's working... I'll certainly rewire everything later but I don't have time enough now so... I must had the 10k input buffer...

Here's exactly what I wired. I didn't plug all the "*" values. It's working nicely like this so...

That winding machine is soooooo Erector-Set  ;D

Erector-Set, Lincoln Logs, Tinker Toys, and LEGO are (were) the DIY training tools!  Did you play with them?

Nice, BTW  ;)

There's nothing really new there... It is just the G-PULTEC with a few added frequencies. The make-up amp is the Gyraff one.

In France, the brand is MECANO. I used my old toys to build the winding machine... I bought a new one now but I have to modify it because the motor rotate too fast and at the moment, I use an old MECANO motor powered by my train (toy) supply  :-*... I have the new motor but I didn't found time to attach it correctly...
BTW, I'm not sure my children toys will help them in the future...
