First of all.
Which kind of lunchbox do you use ? I had some trouble with a Bento2 with the phantom power. The power board had some problems and the regulator fired up two times.

Second:
You had some solder joints who look really bad.
You should definitely resolder some points (there are lot of joints where you can see the gold solder pads)
95% of problems are poor solder joints.
Also use some isopropyl to clean the pcb.

Hi TillM

I use Radial Six Pack. I have another VP312DI (Rev. C PCB), VP28's and they all power up fine, so I doubt if it's a lunchbox chassis issue.
And thanks for pointing out. I assumed if I tested continuity with DMM, it'd be a good enough connection, but I will definitely look over again and try re-soldering some points.


OK! long story involving my wurlitzer 120 and sustain pedal/grounding ,but!

Accidentally shot mains voltage into the DI of my 312. now its about 20db quieter than my other 312. (just the DI, mic input works the same).

What did I fry? nothing looks burnt up.

Not sure but could be a few things. Which way was the pre/post switch set at the time?

I think it was post. Volume is affected both ways tho.

Post would go straight into the 2520. Maybe the opamp is damaged? Do you have another you could test it with?
