[JMS] Millen Project

[myann88 at comcast.net]

Hi Ronnie

I am sorry to hear about your problems with the panel for the modulator!  I know how frustrating that can be.  As I stated in my message about my project, Bill, W2MJ loaned his HV supply for my Millen 90800  exciter.  To be returned when I am incapacitated or gone in either the up or most probably, the down direction!

I homebrewed my 600 volt supply.  Instead of using 816 rectifiers and the neessary well-insulated filament transformer, I bought a pair of K2AW diodes to replace them.  

More when I finish smoke-testing everything.

Good luck with that panel and sensing circuit.

73,

Moke, W2NVR
