Hammond Power supply info needed

I have a Hammond Power Supply built by Hammond of Canada (with a nice
transforner) and have tried both the Hammond site and the VE listed as
Historian with no replies.
Does anyone know where I can get info on the supply
(manual or at least a schematic)?
These wer built by Hammond in the 1970's and they still make transformers
but the actual power supplies.
As I recall these were simple linear power supplies. Transformer to
rectifier to capacitive filter, to regulator stage. Regulator stage was
a 2N3055 or something with a smaller transistor driving it. You should be
able to draw the whole thing out in ten minutes.
