Hello all,

I would sincerely appreciate some help locating the HV/LV power transformer 
T9 for any of the GK500's modulation deck.   I believe it’s the same T9 in 
the A/B&C versions of the 500.  I have the 500C....  No data in the 500C 
manual.  The DC out is +1000 for the 811A plates and +400V for the 6L6 
driver plate.

(So the HV winding is probably 1250-0-1250 @ 300 ma.and the LV winding is 
probably 475-0-475 @ 100 ma.)

Would like to know if someone has a parts unit or a the part number for a 
replacement, if that fails, then the name of someone who could rewind...

Thanks in advance for all help....

Dennis, k0eoo

PS. the problem is the HV windings have leakage path to ground, blows main 
fuse.  The HV has been SS so no filament transformer.  GK500C runs OK in CW 
mode...
