||After you pull the power cord from the power supply, all the removable
panels are removed. This includes the top, the two cheek blocks
(usually located on either side of the keyboard), and the front and back
||The keyboard is detached using four thumbscrews, one at each corner.
Underneath the keyboard is the tape take up box cover, which is a piece of
aluminum with a rolled edge (it is sitting on the flywheel for the picture).
||Now visible, the tapes can be removed by the four thumbscrews indicated
by the blue arrows. First you loosen the yellow thumbscrews which are
on a rod that is drawn back into the tape frame by the tapes as they are
pulled by the tape frame springs. Next the black thumbscrews loosen
the main part of the tape frame and allow the frame to be removed.

- Tape head block cable into the preamp
- Tape head block

||The control panel is held in by two screws.
||After the control panel is gone, the frame is left in there all by
itself...but not for long.
||The main frame of the machine contains the tape path (guides, capstan,
take up box), motor, and motor controller.

With #1037 all packed in the car (well, without the woody bits), Jerry Korb and
I drove to just outside of Philadelphia to meet up with Jimmy, Nancy, and family
for some cheese steaks and suds. We spent some time in the basement
working out some tunes for the workshop. And we toured the area a bit,
visiting the historic Brandywine area, courtesy of Jimmy's fine hospitality!
First things first: Some prep work for the
