Weird Behaviour of VAXstation 4000 Model 60 Power Switch

This machine acts oddly. After powering it off, you usually can't power it
back on again for about 30 seconds or so, it just seems to ignore the power
switch. Similarly, if it has been switched off at the front power switch, it
will switch itself on after maybe a minute of two of being switched off. In
all other respects the machine seems fine. I have not opened up the PSU at
all, just wondering if anyone has ever seen this and might know what the
problem is?
