operation for the oscillator in an unused 5370 to stabilize its drift rate.
Once stabilized,  the 10544A's in the 5370A seem to be much LESS drifty than the
10811's in the 5370B.There are three mods that I do to all the 5370s that cross
my path.  First I replace the fan with a 12V 120 ma brushless DC fan driven by
the 10V supply.   Second I drill a hole in the top of the case over the
oscillator tuning control.  Third,  I add a switch to the oscillator buffer
board to disable that STUPID oscillation detected LED that spew put 5 MHz noise
all over creation.  I also disassemble and clean those slide switches on the
front panel.
