It does look much more difficult than the 38-690 with all of those bakelite blocks. I just did most of my PS chassis last night on my 38-690 and there were only two of the bakelite blocks. Pretty simple chassis to recap. All transformers checked out good which is nice.
The worst thing is moving the chassis around with all the wires that protrude from it. I melt out the tar out with the bakelite block still in the chassis...just the wires on one side labeled and unsoldered.
After doing three 16B chassis you get rather quick at doing the blocks.

Good luck with you 37-690. It's a great radio
