I wonder why these Philco sub chassis have so much trouble? It can't be just the fact that it's an RF sub chassis, there were RCA and Northern Electric/American Bosch sets that used similar things and I've never heard a complaint about the RCA sets. On thing that I have noticed about Philcos is they seem to have a lot of front end problems regardless of the chassis layout. Maybe they cheapened out on components where they shouldn't have? I know that in one set I have from the 1940s they used brass plated steel in the IF trimmer screws rather then brass, and that sets like the Philco 60s have corroded coil problems thanks to the plastic insulation they used. David Grimes manufactured sets under his own name back in the 1920s and they weren't particularly anything to write home about.
