Thanks god, my 54542a still works...
This has been a problem for quite a while now, a number of very good Tek
scopes for example use custom IC's that run hot and are unobtainable.
OK, this is an interesting note - but if one does not use
the instrument regularly it should last a long time.
And knowing about this problem one could implement better
cooling by e.g. a small fan.
With EPROM and FLASH its worse: The charge on the floating gate
degrades and renders the device useless independent of using it
or not :-(

Which Tek's are likely to encounter this problem?

Thanks,

Erik.
