[Amps] Amp Supply LK500ZC info needed

[Dave NT9E]

   A few months ago I bought a used Amp Supply LK500-ZC amplifier and need to
   re-wire it for 120v operation. The manual that came with it was not the same
   model. It was a "ZB" model. And the conversion info in that manual shows a
   diagram that  looks nothing like the "ZC" model I have, If you can part with
   a  pdf  copy of the manual or know where I can purchase a manual for a
   LK500-ZC please let me know.
