Check only socketed devices. Do not desolder unless you have good
reason to believe the part is bad.
Hint check for 5-6V on the power pins of the ICs.
IF you have the manual, check for all the voltages.
The only problem with the CRT is finding a replacement. THey may be
more common than thought. Haven't checked in decades.

THe batteries are charged? (about 6.6V or more full charge)
Since you replaced the batteries did you check the fuse?
Yep, good. Also the 4066s
Hmm, all mine are soldered in.? Do you suggest I desolder and check?
sometimes get cranky and/or the sockets.
Only one '00 has a socket.
The tough fail would be the CRT. Check the heater pins with a multimeter
to see if its open (unplug it as there is a transformer winding across
it).
I'll check. Mine needed
one when I got it but they were available then (1977)
from NLS. Side effect of the hammer mechanic owner.? Now it would be a
hunt though old tube brokers.
Yep, I know that'd be the main issue, but I am
hopeful it's something
less problematic.
