Thanks Richard but not quite as I have nothing, no signal on RF OUT when viewed on my 'scope? |
Ah, not so good.
Have you checked whether RF is present upstream of the attenuator, notably at the plate of V2B? (with the output of C25 lifted and taken to GND via a suitable resistor).
I would check all valves are connecting with their bases - I have had three awkward-to-trace faults caused by intermittent connections.
If still not OK, it's probably back to basics - checking all voltages throughout before delving in any further.
