It's VERY common. In fact, it's pretty much the rule for old Tektronix
scopes IMO. Come over to Sanford, Florida and I'll show you several HUNDRED
Tektronix scopes and AT LEAST 95%+ of them have aging problems (bad caps,
brittle plastic, intermitant switches, etc. I recently pulled out a dozen
of so 465/466/475s and I didn't find a one that worked properly. In my
experience, sitting unused is death on a Tektronix scope.
I have an old 465 that seems to have died from loneliness... it has a
dead short somewhere in the PSU such that one of the internal fuses
blows violently. I keep meaning to get around to fixing it (it's my
newest scope (of 4)), but just never mange to do much more than prod
at it.
