[ForSale-Swap] Lookingfor Brodhead Garrett Schematic

[Richard]

I am looking for a schematic for an old Broadhead Garrett Model P-4
power supply.  This is a variable 400V/100V/40V/Filament supply used
back in the seventies in high-school electronic labs.  The manufacturer
would not send me one due to age and considering it a safety hazard.  Go
figure.  This would make the repair easier than wandering though the
thing.  I use it for hollowstate projects.

Any help would be appreciated.
