Hi, Jimbo.

A small part of what you seek might be found at:

http://www.localdial.com/users/lawrence/apf.htm

An all-pass filter arrangement for phase shifting at 60 Hz would be easy to make. Just notice though that in the first schematic at that site, that C3 and R4 could be interchanged and you still have the all-pass effect.

Do the transfer function analyses to see which form of filter would serve you best.
