I am still very sceptical of the ganged VR3/VR4 pots. The shaft is running at an angle and no longer fits in the intended slots. Given the hand-built nature, I guess this could have been done by Moreton Cheyney, but it would be worth checking the mounting plate to see if it has been added/moved. It also seems highly unlikely anyone would design it with the phase-splitter on a separate chassis to the power output.

This is a small manufacturer with a standard design who may have made modified 'specials' to order, and then it appears this one has had post manufacturing alterations. This leaves you with a dilemma, do you try to get it working with minimal number of 'fixes' in the hope of returning it to the state it left the 'factory', or try to work out the original standard circuit.

Is it possible to identify soldering that has occurred post manufacturing?
