Here's what I found inside when I pulled the chassis.

Tube lineup - 80, 24A, 56, 24A, 35, 6H6, 6F5, 2A5, 6U5. Not exactly stock!

The most confusing modification was the 6H6 and 6F5 tubes because there's no 6.3 winding on the transformer secondary.

Nice blue Acrturus globe 56 where a 27 should be.

Finally, here's what I found underneath. What a mess! The IF and LO on the right seem original, but the rest has been radically altered. Two multi-section box caps, a filter choke, tapped bias resistor and most of the bakelite blocks are all gone Instead, I have a few new caps one power resistor and a small 6.3 VAC filament transformer.

So what do you guys think ? it's already been suggested I just start looking for a new 90 chassis rather than attempt to restore this one.
