Finally got my Brownie!

I have the bigger/regular version that I have used for years and hauled to gigs. Works great. However, since I generally have one amp on stage, I don’t need the extra capability of the regular version. With the smaller Brownie, I run my Velocette at it’s intended 115v and it sounds great.

AmpRX Brownie

Excellent product. Built like a tank. Easy to use and it does the job as described. My wall voltage varies from 121 to 125, as such, the Brownie is a big help keeping my modern amps in the sweet spot.
