Boob Tube v 1.5 * Valvecaster Variant *

Based on JuanSolo's 12V Boob Tube which is a Valvecaster variant, but here with a 33 - 40V supply via a charge pump.  Make sure you choose appropriate 50v capacitors for the voltage. 

Here's the charge pump, if you supply it with 12V you should get close to 40v from the 33v output point. 

 

NOTES: If you want to supply the charge pump with 9V to avoid using a 12V adapter, you could use a 12V regulator off the 17V rail to provide the 12V required for the heater, or maybe even a voltage divider from the 25V rail.  In this instance you would only get around 33V for the plates though.
  

Yes this is verified, and it sounds great!
