I acquired a HP 8018A serial data generator, a very
nice piece of equipment.
But after a little time the power supply heath sink is getting hot about 70
degrees Celsius (158F).
I'm not sure if that is normal, anyone who can help me with this ?

Older equipment should have power supply (and elsewhere) electrolytic
capacitors tested/replaced as the average capacitor life span is only a
couple of thousand hours (2,000 hr). An ESR meter might help here...or
feel the cap after the machine has been on a while (turn it off before
touching!), and any that are hot to the touch should likely be replaced
as suspects...
