Bloch wall disconnect and reconnect. The final design!

I believe the little video transformers the Sauron posted are the matched pair traffos and the 2 transformer tests also.

     @ Bolt:
      If you have any pictures or images of the Magamp, and how it would look incorporated into a TPU,  would be good to see. Can it be set up to start with a capacitor?   I don't get the part about the 5khz driver, can you explain a little.  What would the magamp look like for lets say a 15 inch SM type TPU?  I'm trying to get an idea on how to replicate the 15 inch SM type using the magamp, would it be anything like his? As his does not show any other components other than a capacitor or two.

@Bolt,
Well you started a landslide...

Do you have the scripts for the schematics? I know you said you don't keep them but I thought I'd ask. I see the traffos in a flipflop configuration so they would ring back and forth. With the scripts I could put test points in and verify. Would just save us time.

Thanks.

The magamps are the little toroidal things sat on top of the control box in several TPU variants. As i said many times you don't need to use them at least not at first. They are the "icing on the cake" when everything else is working perfectly as it does away with power fets.  So i STRONGLY suggest you dont start messing with this as no one yet has the full tpu working. In addition the bias is set higher up the non linear portion to force the device into Class C. This is why SM use a magnet beside these cores. We don't want class a b etc as this waste drive power but for now don't worry about these tiny details. You only need this when you want to make TPU without any power source whatsoever and hardly and SS devices. It will start with one swipe of a magnet on the collectors.

Oh I forgot the magamps only work on AC or Square drive as the power source they can't control DC. SO if the power source is 5Khz clock then this signal will sit ON TOP of the main DC o/p. Its the sound you hear on the SM vids and the 5Khz MUSH on the DC o/p.

Sorry no scripts i post these in public a while ago then i just move on to other stuff. Only take a few minutes to rebuild the sim and copy my layout but please DO NOT get hang up on magamps because till you have a working TPU this is something that SM may have taken months or years to perfect after moving away from SS device and TUbes.
