Hey RodB, Per the schematic David was kind enough to supply me on page 1, which is a match to this chassis. C25 and 26 are together in the schematic and part of the AM,FM, Phono selector switch circuit. Agree a general tune up is needed but I also have a lot of noise even on FM. Next replacement is the power supply electrolytic caps. They tested neither open or shorted so I left them alone till I got some life to the speaker. Also since I remembered this radio had been dropped at one time, guessing a few more new tubes may be in my future. Still have two tubes that remain dark even though they have filament voltage. One in the FM section the other in the AM section.
