Yes, very odd symptoms. A smooth loss of power.
The longer I think about it the more I start to believe that it's not a faulty connection / contact but some electronic parts are about to pass away. 30 years are a long time for those components. Unfortunately electronics are no my strong point and I don't know very much about the changes a faulty but not already dead part may cause.
But I do know that
- 30 year old electrolytic capacitors are prone to failure and
- output voltage without the capacitor bank would be significantly reduced.
Electrolytic capacitors dry out over time, they may be already out of specs and not working properly.
If you disconnect the capacitor bank voltage should only be roughly 0.7 x your previous no load readings.
1= 18.7v x 0.7 = 13.1v
2= 21.7v x 0.7 = 15.2v
3= 23.4v x 0.7 = 16.4v
4= 25.2v x 0.7 = 17.6v
5= 30.8v x 0.7 = 21.6v
6= 33.7v x 0.7 = 23.6v
If your readings are noticeably higher than expected you may need new capacitors.
Nevertheless I would prefer a second opinion from someone who's more into electronics before starting that check.
