[Hammarlund] HX-500 power supply service bulletin

[Al Parker]

Hi Jeff,
     Here's the info on the p.s. mods, which incl. what you wanted, on 
the rectifiers, plus the change to an improved pwr xfmr.  I can't 
remember if my HX-500 has the better xfmr or not, but it does have the 
rectifier mods.
     The .pdf att won't get thru to the reflector, but if anyone else 
wants it, send me a note.
     I hope it helps.
73,

the 12 AX 4S and the 5R4, along with a semiconductor device for the bias 
supply.
