Parasound P/ld 2000 repair/upgrade

Hi apologies if I break forum etiquette but its through ignorance as Im new to this.
A failed diode has blown out the transformer in my parasound P/LD 2000 pre-amp. There is no info on old unit. So was wondering if anyone out there has secondry winding info so I can get new transformer wound. Am planning to run 3 toroidal's 1for left 1for Right channel and a small other for ancillary circuit. Then fitting them all out-board with shielded umbilical.
So HELP anybody anything? stuck in isolation and no sounds Ahhhh.
