Finding the "sweet spot" on the variac linked to the gain and volume settings on the amp takes a little bit of experimentation, however, the end result has always proven valuable in terms of …

21. Okt. 2022 · Since the MXR Variac fuzz is a Band of Gypsys Fuzz Face with the additional tone and variac knobs, would it be a better idea to just get the MXR if I'm looking for that same fuzz …

25. März 2012 · A Variac does indeed have just one winding. But it doesn't have a rheostat. The knob controls a brush slider which moves along the exposed winding to vary the tap point and …

13. Mai 2016 · I was in my teens some 40 years ago and somehow managed a 3A Variac for free and a 1 KW isolation transformer for like $10.00. I added an Analog voltmeter and ammeter as …

19. Aug. 2018 · Hello there, A variac is a transformer with variable secondary winding turns. That means the applications are almost endless. Since in it's main uses it lowers power to AC …

22. Juni 2008 · The variac is used for a couple of things, but by itself with no other test equipment all you can use it for is to slowly bring up the power on an amp that has been sitting. What this …

8. Mai 2017 · Hello! I'm building "isolation transformer+variac+dim bulb tester combo" according to plans in attached pictures (from "Mr Carlson's Lab" YT channel - It's gonna be enclosed in …

13. Jan. 2015 · A rheostat is a variable resistor and a variac is an adjustable auto-transformer. Not likely to make one from the other though they both can vary a voltage but using very …

9. Mai 2011 · Right, got it fixed, I disassembled the variac and cleaned all the contacts (primarily a wavy copper ring that was really dirty) using sandpaper, an eraser, and acetone.

27. Dez. 2017 · Variacs are not isolated from earth. The variac pictured can put out 130V ac, referenced to earth ground. An isolation transformer is not referenced to earth making circuits …
