While waiting on parts for another project. I decided to start on the Philco 90 I got last Friday.
I pulled chassis to size up what will be needed and what was done in the past.
Looking under chassis I found that 2-bakelites have been replaced with solder tabs with tube caps.
Note the two solar in top left they replace a double bakelite block.
Most of the other bakelite blocks have been by-passed with external tube caps at least the old ones were cut out of circuit.
The Ecaps have been replaced at some point,but old ones were still wired in. I pulled the tuning cap off and was wondering how to best clean it? It has the trimmers on each side and I would not want to damage them. Sorry if pics. are not in order. Thanks for anyhelp.[Image: http://i1336.photobucket.com/albums/o654...21a5f1.jpg][Image: http://i1336.photobucket.com/albums/o654...7a3dd8.jpg]
