Philco 97 - RF problem... HELP!

Mine is not the same as yours Steve.   See that cap block up there in the very corner beside the 85 tube in mine.
Well it aint in yours.
I am now thinking mine is an American model 98 chassis after all.   Which would mean I have a Philco 98 chassis in a Philco 98 Cabinat.  WOW.

I am off to get a 98 service sheet.   Chow.

What is the block there for?  I have the mounting hole - but not the block.  That looks like a resistor on the side of it - is it decoupling the cathode of the 85?  I can't quite see in the photo... The 97 circuit shows the 85 cathode straight to the chassis which is how mine is.

The service info for the 97 doesn't show everything in exactly the right place.  There is a cap block with two 110pF caps (mentioned above) on the side wall of the chassis - the service info shows it on the bottom of the chassis the way all the others are between the 85 and the ANT coil.  Yours is in the same place as mine.

Interesting... they look very similar, I wonder what the actual differences between yours and mine are - seems more like a code change difference than another actual model...

There are no personal problems that can't be overcome with the liberal application of high explosives
