[Drake] SP-75 Question

[Fern Rivard]

That removable plate is in there to make access to the bottom of the printed
cct should you have to service it and take some meter readings. This way you
don't have to take it all apart.  Fern

attached with four screws.  It is a little smaller than the chassis, but not
by much.  One would assume that it would give access to the bottom of the
circuit board, and it does.  But there are no apparent adjustments that one
needs to do, I think.  What is the purpose of this panel?

remember, it was assembled in the late 70's to early 80's.  Very simple
assembly and the board easily slips in and out of the simple chassis.  The
manual gives a tuneup procedure with test point access from the top side
after you remove the chassis cover (not the panel).
