Philco 97 - RF problem... HELP!

Ok, I'll play with clearances etc once I get the chassis finished and can try to line everything up again properly then.   Thanks for the info

The chassis has had a few capacitors replaced over time but all the bakelite blocks are there by the looks of things, so I spent a day just replacing smoothing caps and rewiring things back (mostly) where they belong.  I decided to not restuff the main caps because only one was there, and because I don't want to fully restore this (not yet anyway).  I mounted two caps on some tagstrip and bolted that to the side of the chassis through an existing hole.  Fully reversible but also fully functional.  When I get around to a full restore I'll restuff probably... maybe.

I did restuff the little can which has one 1uF and two 2uF caps in it with a 1 and two 2.2's simply for space reasons - and it gives a nice tie point for them.  The finish isn't perfect but I didn't want to cut the can under the clamp in case it slipped out of the clamp at some point in the future.  I could probably have just done away with it entirely...

Most of the resistors were well over spec as well, so I replaced them (is it just me or are the Philco style resistors with the pointy ends almost always still bang on value? The 89B I did had a few and they were all perfect too). 

I used poly caps because thats what I have - seems to work well (any thoughts on poly over electro in this particular application?  The relevant part of the schematic is here:

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