There is no regulator chip in the unit. I am thinking that this must
be a 5 volt unit.

The 82 series came in a lot of flavors. I have one 82-49 which is
definitely 12V ( draws 0.12A when warm and maybe 0.3 when cold) and
has a 5V pp square wave output at 10 MHz. It also has a Vref output
and an EFC input. What is odd about this one is that it came to me
from a TRW swap meet scrap dealer who bought stuff from Cubic
Communications in San Diego and it had a "Reject" tag from them.
Probably because it was supposed to be a 5 MHz unit as marked, so
presumably had the wrong crystal fitted by Isotemp. Other versions of
the 82 series (-10) were fitted to Racal Receivers like the
RA6790/GM. Screw adjustment on the side and 5 MHz output.
Are you sure yours shouldn't have a 5V supply on that output IC? Could
be why it died if there is an internal regulator that failed putting
the full supply voltage on the IC?
