Caboose OverDrive

[Aria51]

Mine sounds like a tube amp, those last few seconds before the caps discharge.
I've swapped the IC and if I flip the 2n5088 I get voltages that are more normal for an NPN but the result is the same.
Any ideas, anyone?
If not, I'll wait for the build doc. I'm pretty good when I have a schematic.
TIA

Pray for build docs.

I looked into it and the Caboose is based on a Vertex product. So it's not supposed to work. Sorry about that.

All fixed. Vref on Pin 5 of the IC was missing. I damaged the foil between the junction of the voltage divider resistors R1 and R2 and the IC. Sometimes I drink beer and watch Netflix while soldering.

Sounds dangerous.

I'd still like to see a schematic.

And BTW, The orientation of the transistors was not part of the problem. When the 4.5v VRef was restored, everything else came back to life.
