The last few days has been a rebuild of a R27 Timber Empire state.
The only circuit diagram I have has been photocopied that many times it may as well be spaghetti.
So working with that to trace the circuit and a good R28 circuit I got the job done.

Interesting that the resistor network around the local/distant switch matches the R28 setup, so maybe late in the production run? Over-all the same circuit with a 78 instead of the later 6D6.

BUT.. someone had been fiddling around with the coils and tuning gang, not even close to what it should be.

and then... no reception. So what do you do to every tuning cap in sight? Do them up tight.

I managed to get it running reasonably well by ear. Both my sig-gens are playing up. I'll re-visit it later in the week and align it properly.

I think I have about 20 hours invested in it so far. Next the cabinet.

It sounds as though it belonged to Homer Simpson

Long ago I had a beginner's book "Electronics for Everyone", which mentioned such screw tighteners. It mentioned that repair technicians had a term for such people, "but it's too technical for this book"

In a pinch, you could tap the IF (at the detector diode) from a good radio that has the correct IF frequency. Tune that radio to a strong station, and feed that radio's IF to the broken radio's IF at the converter stage. Then you should be able to get that radio's IF close to its proper IF frequency. After that, you could use local radio stations of known frequency to get the front end and osc circuits correct.
