Theta Data Basic II clock

[mravinsky]

Has anybody upgraded this transport´s clock with an aftermarket one?
I need some guidelines about how to do it.

Nobody has changed the clock?

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.

You can push a grommet or rubber band or ring etc around the crystal too.

I also preferred the sound of mine with a standard IEC socket wired in instead of the device with the built in filter but then I am really not a mains filter fan.
