I might help you, just let me know the problem.
I serviced this product in the past and most of the problem were due to the mosfet in the signal path.
If you disconnect the o/p cable with the pre not muted, the mosfet is gone!

The transformer has three secondary windings. 275VAC/30mA on the red, 20VAC/25mA on the yellow for the opamps in the PSU regulator and 11VAC/400mA on the green for the filaments.
