Attached is a schematic for a power supply for the Grado RA-1 amp. Does anyone have any comments or suggestions?

Is this something you're proposing, or is it an existing box that you want to upgrade?
If it's existing, are you having any problems that you want to solve?
A full-wave bridge rectifier would be a place to start, instead of the half-wave shown. You'll need a different, centre-tapped transformer.
Check the www.headwize.com site for projects that have power supplies for ideas.
