Variac before or after Furman PF Pro.

Post by Thermionic/EL-34 »

I bought a variac to use with my 100 watt Marshalls.
Thinking of running at a steady 115VAC.
I have a modified 1978 JMP 2203 & a JCM-2000 DSL 100.
I also use an older Furman PF Pro.
Should i plug in the variac at the wall AC outlet then into the Furman then to amp or Furman into wall, variac into Furman & amp into variac ?
The Furman is rated @ 12 amps.
The variac is rated for 5 amps @ 500V.
Im guessing AC outlet > Furman > variac > amp
Thanks.

After the Furman.
When I die, I want to go like my Grandfather did, peacefully in his sleep.

By the way, I can't see how your Veriac is rated to output 500 volts.

It can be confusing to say the least.
