my ruggizied high two 647 (w MOD165 ) break on weekend down.
This 647 has improved high voltage transformer (120-0846 instead 120-0332), but it's not helping him.
Winding short !!
647 is a rarely bird = getting a good trafo is nearly impossible.
But, chuck from yahoo group has giving me data of hv transformer.
Look, my terrible jobs. shit-calcuation, i needed more space, more than calculated.
shit-counter, don't counting up ever. (now have i too much post accel.)
it running too good, that regulation don't working. ( i must putting one 39OHm between basic and HV transformer) I has a good running 120-0332 with too high post acceleration voltage (~14kV instead 11,8kV )
I trimmed my 647 2,2kV cathode voltage to 2kV, it is better, because i have too many post accerleration voltage
BUT I AM GLAD Best regards an big thanks to chuck.
