Indeed it is based on Mr Watterson's ideas 
it does work well.
The 4k7 is what was in the chassis originally feeding g3 through the oscillator coil primary, I guess its there to stop the windings from having their own peaks of resonance, in the ER it was taken from the feed to the IF valve screen supply...
The mod did work very well, though that chassis is pretty fair anyway, for a cheap and simple set up.
The first IF did need peaking a bit, the whole alignment would need doing if it were to be left, seemed to favour the extremes of the MW... Not miles out though.
Amie.
