Schematic shows the emitter lead of the final transistor is grounded. Won't get a voltage reading there.

Are we really talking about the collector? The center lead of the final and driver?

Checking what comes out of the emitter at TR41 would be next. Center lead is TR41 collector, should have full power-supply DC voltage there. The lead towards the front is the emitter, and should have the DC voltage set by the carrier trimpot there. The base lead, towards the rear should have that voltage plus about 6/10 of a Volt. The difference between base and emitter should remain around that 0.6 Volt no matter the base voltage.

And if you do have a normal six Volts plus or minus on the emitter of TR41, the mode selector and/or wires leading to/from it are all that remain to blame for no voltage at the final and driver collector chokes.
