17.014 My GS power supply seems to be nearly dead! The only odd looking symptom so far is that one of the big electrolytic capacitors near the power input side is at 260 volt & the other is at 30 volt?!

There is a 100k bias resistor in the front end of the inverter. If this
resistor is broken, loose, or otherwise 'open' you will get the symptoms
described. Replace the resistor and both capacitors should be at the same
voltage ( approx 140 volt) and within the 200 volt working rating of the
capacitors. This should fix the power supply.
