Rotel 965bx LE discrete

I wonder if anyone here can help me. I own two of the above machines which are absolutely stunning - real improvement on a current Arcam FMJ sacd 37 at £1400!

If you see one buy it.

Trouble is came down the other day and one was just reading error. The motor was not turning and while laser moves it is not on. Having a standard one around I swapped lasers and motors.. To no effect.

Can anyone help with some ideas and if possible send me a service manual to [email protected] - kind of struggling here and really want to get this fixed.

Any simple mods to further improve also welcomed - I will fit a rock clock and psu at some point. Obviously the discrete output board and tons of black gates all help...
