Threshold SL 10

Have acquired a Threshold SL 10 preamp. All original since day it left factory.

I know just by age the caps should be replaced. My question is what are the values of the caps on the board? Also what value for the caps in the separate power supply and where would one find those huge Mallory caps?

Any other pertinent info would be helpful as well. It is operational now and sounds great. Just want to make sure it stays that way.:)
