Deeptronics Freeze pedal Troubleshooting

[pbrommer]

Okay, so this past weekend I’ve been batting 0 fer every single dang pedal. But this one has me a bit stumped.

When I take out the diode from the DC (which goes to the 3.3V regulator), I get normal voltage but obviously nothing to the rest of the pedal. If I reverse it, I get about 9V on the DC on side of the diode and then about 0.5V on the opposite side. If I put the diode in as shown, I get a voltage drop to 3.3V in and about 1.5V to the TL072.
(This is all without the main module installed)

The voltage regulator gets extremely hot with everything installed normally. Reversed, no over heating.

Any thoughts? Maybe the voltage regulator is mislabeled and backwards? I tried shorting the diode but I got the low input voltage (from the actual dc jack area while testing) issue. It’s definitely something in that voltage area, but I can’t pin it down.

I turbo-dumbed it again. Grabbed the wrong regulator. All the voltages are correct.

Right on, was just curious to see what orientation you had it on. I still haven't gotten mine yet so I was wondering how much space there was.

There’s space, but it makes me nervous because the tab has the 3.3V flowing through it. I put heat shrink on it for safety. I’ll post a build report since it’s up and running.
