When setting up my new build https://el34world.com/Forum/index.php?topic=26103.0 (https://el34world.com/Forum/index.php?topic=26103.0) I found that 115v on my variac dialed in my voltages nicely. I found RobRob's plans and decided to build a fancy version for myself. RobRob's was stripped down and dirty. A while ago, I was looking at vintage sound workbench dot com's products. What I didn't like about them is the ugly Chinese meter. I put one on my variac, but one was enough. That was utilitarian, I wanted something a little nicer if it was going to be hip-to-hip with my new amp. I had a few of the parts and a cool military NOS meter that I was going to put in the stereo console that I built a while ago - never put it in.
The specs:
Box: Hammond 1411P (6"x5"x4")
TR: Hammond 166N12B
Meter: Simpson Model 157
Light: 110v Fender style w/ 47K resistor
SPDT front selector switch for ~115v (right) or ~108v (left)
Handle: Emtek Warwick 4" on centers
Lastly - a tag. I designed the tag and had it made by AwardsETC on Etsy who has done similar amp-style tags. It turns out Vintage Voltage is the name of a UK car show. The URL is not available. I will keep this for my personal use and not sell it worldwide to become independently wealthy... :icon_biggrin:
