I've had my M^3/STEPS done for a couple of years now, so I thought I'd share some pix, now that have a digital camera.
It's now in its final form, having been through a couple of changes from my original ideas, which is why there are so many extra holes in the baseplate. First, it had a crossfeed board with a rotary switch installed, but I didn't like the effect, so I removed it, hence the plug in the faceplate. Second, it had a Hagtech Bugle phono board installed, but after struggling with hum, I removed that also. I eventually solved the hum issue by moving the selector switch from the faceplate back to its current location to shorten the input wiring. Here's info on things not obvious in the pix:
STEPS output @ 24VDC.
Electrolytic caps are Muze KZ.
Bass boost caps are Dayton (Parts Express) film and foil.
Opamps are 637BP L/R, 627AP ground.
Parmetal case 16x8x3, anodized front, painted top/bottom.
The shaft extender was DIY, the parts sourced from Ace Hardware.
Signal wiring is silver plated copper, soon to be replaced by Vampire OFC copper.
