RE: Zerozone 100VA PSU Fuse Issue

"I have no way of confirming the appropriate fuse rating for the application."
You do have the means to check the output current draw however. Since it's low voltage DC put a multi-meter, set to amps, in series with the output and turn things on. At turn-on you will probably see a momentary spike as things charge. To do a thorough check make sure all equipment downstream are discharged, letting them sit or through a bleed resistor.
The spike may not blow the supplied fuse immediately, recall you told us there were extended periods before there was trouble. it's probably at it's limit and repeated turn-on fatigues it.
I would bet a slo-blow fuse fixes your problem. I would use the fuse closest to the measured output current draw. You want to protect your audio equipment more than the power supply.
