Three of us at our museum attempted to remove the chassis for a 1936 645K art deco console, only to be stymied and mystified.

There are two rear under-chassis hold down screws, which we removed.  After pulling all the knobs, we attempted to pull the chassis
to the rear of the cabinet.  It wouldn't budge.

After carefully eyeballing the cabinet from the front, and also from the inside, none of us could see any screws that appeared to be holding the chassis in place.  Yet, further tugging with more force had no effect.

I guess it is possible that the chassis is just seized to the wood and we need to coax it harder.  But, if someone has a better suggestion based on experience, we'd sure appreciate your guidance.

Thanks in advance for any helpful replies.

Other than the screws from the bottom (typically 4) and the knobs there is nothing to hold it.
It could be seized. Try to gently rock it, see if you hear that crunching noise of crumbling gaskets. THose are made of some sort of rubber that in time hardens and glues to what it was touching. You probably just need to try to run a large flat scredriwer between the rear of the chassis and the shelf it is mount on, lever it up, and see if the chassis will start moving with that crunchy crackling noise.

It looks like this chassis is similar to my 650X. There's the 2 Bolts at the back and the knobs to remove. There's two locator studs on each side of the chassis front. The bottom ones are bare and the top ones each have a large rubber shock grommets. In addition, the 2 chassis bolts went through large rubber grommets that can drop out the bottom of the cabinet cross member support. Try shifting the rear of the chassis back and forth.
