Try another analog meter--a good one will agree with your digital--then again--your digital meter could also be wrong. I would want to know which meter was correct. I have four Fluke meters and they all agree to about .2 volt measuring 120 VAC. Measuring AC voltage is more difficult, but meters should agree on a 60 hz sine wave. Things get difficult at higher frequencies and irregular waveforms.85 degrees C--well I think the room would have to be on fire for the underside of this guys amps to get to that temperature. The highest temp I could ever imagine these caps getting would be 40 degrees C--about 105 degrees F. So what would be the life of an 85C degree cap at a temperature of 40 degees C?
Exploding electrolytic caps are nasty, and sound like big firecrackers. The Solens are film caps? They would probably be self-healing in case of a dielectric puncture? Unplugging power tubes sounds like a good way to get burned and cause caps to explode. This is a standard practice in antique radio repair though. Pulling tubes to isolate a problem is common.
