Unless you have some kind of unusual fiber optic probe, you won't be able to see anything with respect to the tube sockets just by removing the tubes. You would have to invert the amplifiers and remove the bottom panel to get a decent look. Since my own MA240s use the MA2 chassis' and power transformers, I know how humongously heavy and awkward they are to manipulate, so I predict you will not want to do that. However, do take a good look at the tube pins and let us know what you see. Try scraping the pins to see if there is a filmy gunk on them, i.e., varnish. Also, see whether the filament pins look any different from the other pins, i.e., corroded or otherwise deteriorated.
