Philco 90 with Twin 47 Tubes in PP
#7

Bob

In this case you can go with whatever. It won't change much at all.
We tried to figure it at some point with my version of 90, and the sch, my chassis and another person's here chassis, all three had different values.
Also the chassis diagram had the capacitors in tin cans swapped.
Also in my case there was a right value cap used in one place but from another item on the sch (another dual cap).
And if you look at this sch (your link, 2x45 version) the cap next to the resistor #47 (on top the osc tube) simply does not exist.

So.....
