I cannot do a complete Calibration and reset procedure, but on DAC calibration with Manual On and toggling Tape Enable off and on, I only manage to get LEDs 1 & 5 to light up.

Changing VR6 & VR7 do nothing.

It looks like a previous member's issue, and it was recommended by Andy to reviews D05-D07 especially, so this is my next step.

It looks like the 4051, even on boards 369 and 370 might also need to be checked/swapped.
