Nicely written and paced!

The capacitors are in series with the 4 ohm 50W resistor and create a high pass filter.
The use of these series capacitors is discussed in some detail on [Tutorial] Building your own DIY E-Stim Stereo Device.
They must be bipolar capacitors. If you want to change the cut off (-3db point) then you ...

Thanks for your comments. Parts list in spoiler.

Great idea, really well written, we enjoyed this story immensely

Finally got around to building a stereo E-stim unit based on the info in this thread.
This has a triphase switch, a Channel B invert switch and a switch to disconnect the output terminals from the transformer outputs. It has leds for power, triphase and channel outputs.
It also has a remote to turn ...

Thanks to the creator of this fantastic video, great editing and well paced.

Thanks also to edger477 for one of the very best (for my setup) estim mp3s.

These two together never fail me!

First a big thanks to phx for this amazing video & storyline and lolol2 for the estim.
I have played this many times with great results.
However phx's choice of models was not always my optimum so I have re-edited and replaced some with models I prefer.
I remade the white text at the top of the ...

Well this was fantastic. I thought the original Estim with Liya Silver was very good but I had edited it to add a low level estim during the red sections as they were quite long without any stim.
However you have gone better and improved the whole thing.
Well done and thanks!
