        Also.. someone posted the voltages that are supposed to be present for
the tube:

        Correct
Voltages                                       
Mine

        Pin 1 - Filament GND

        Pin 2 - G1
30V                                              
34v

        Pin 3 - G2
410V                                            
202v

        Pin 4 - G3
300V                                           
127v

        Pin 5 -

        Pin 6 -

        Pin 7 - K
94.5V                                            
20v

        Pin 8 - Filament
B+                                    
6.3v

         

         

        my voltages are about 1/2 what they should be.. Im going to yank the HV
and have a look.. Does this seem like a flyback issue?

         

        Thanks,

        Andrew
