It probably would hurt to run the tube though a tester just to get an idea what kinda shape there in. The last couple of big chassis Philco's I've serviced had several under performing tubes. Like it in 30% range. For good performance around 70% +. Replaced them with some tested good used tube and it made a big difference. Mostly the 77's and 78's.

There's two electrolytic cap behind the 42 tubes.

Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
