Some guy on the barking dog forum Had a picture of a 37 or 38 he did. He unbolted the tuning dial and took all the screws out of all 4 of the sub chassis. thing folded up like a rubics cube. Got to everything without unsoldering anything from the 4 sub chassis.

You can do that on some of the lesser models. But, I can see no way on the 37-116. Wires come in from 3 dirrections and even thought they are not rubber coated, they can be a little brittle, so best not to twist them any more than needed. Really it only took a few minuts to take it out and not much more to put it back. You just have to make sure that everything is back where it started.
