yikes, that thing looks snug to work on. And I thought my Sherwood was bad. I have a Knight stereo preamp from around this time, and its also assembled like a complicated German car. Tight quarters, lots of things in the way of everything, and it only fits together in a very particular way and in a specific order.
The Fisher MPX-100 is just as bad.Yes, it is a little tight. But this little guy is point-to-point with no printed circuit. With the assembly manual, it is easy because you build up the layers. Now if you want to get close, work on a Sansui 1000A, Scott 340B, or Kenwood KW-1100u. The Japanese must have small hands.
