I never tried it but think all you need is that link to Geofex, better even than a Variac which don't weigh little either and can be accidentally bumped to like 140V.
Thanks. I realized I have three Furmans, expensive ones.
But, one needs to add a variac type device after the Furmans
and before any devices receive dirty voltage/wattage/amperage.
Just want to get something soon. The four I'm looking at are
all between $200 and $300. I might get a heavy duty variac
for my home on a permanent basis for all expensive electronic devices;
and a lighter variac for travel and gigs.
I won't worry about someone turning the voltage up, as I don't worry
about someone throwing drinks on my amps, etc. Things happen.
Hey! ~ a valued vintage amp could blow a transformer or output tranny
or a set of capacitors or a speaker, right?
