Good morning Jac, many thanks for your kind offer, these valves are always welcome. PM sent.

Before any servicing work is done to this set the line output transformer must be warmed up by passing a current of about 20mA through the EHT overwind and primary. This procedure has been proven to be effective for driving out any moisture in the windings.
It's fifty-two years since I serviced one of these sets.
