Older amps expect 117 even 110V from the wall. I have 125V and 129V is reported.

It *looks* like you tell the Line-R box that your line "is 110V", and it transforms 80V to 130V into 110V +6% -12% (97V-117V). I'd think the 600 Watt model would be ample for any single amp from 110V days. (Even an 80W Twin can't suck much over 320W from the wall.)
