You mention that you get 'static' from the loudspeaker. With the circuit working correctly you should get a roar of hiss.

Sound take off is from the collector of VT5 the final if amplifier.

I would take a look around VT1 the AGC amp transistor and the preset contrast pot R2 4K7.

I presume you have eliminated VT2/3/4. John.
