Re: [TCML] Power supply question

[Bert Hickman <bert.hickman@xxxxxxxxxx>]

Hi Paul,

Probably... however, you may want to connect a small low pass filter (HV 
capacitor across your HV power source and a tiger stripe HV resistor or 
a 100W+ wirewound HV resistor in series with the Marx HV input) to 
prevent high voltage transients from backing up and killing your HV 
power supply. As you likely already know, Marx generators love to kill 
nearby electronic devices, including the charging source.
