The std clock cct is already a step up from most. Change the associated caps with silver mica ones. The difference between 1 and 2 was a separate transformer and psu for the clock.....
Do you use yours co axor aes ebu? If aes, change the resistors near the output transformer to 56 ohm or 55, they are now set as 37 to make a 75 ohm balanced out. At the time of design there was doubt of exact consumer balanced audio output standards hence the 75 ohm set up.
