Just a quick post about the power supply. The LM333t replaces the 337 (neg) and the LM350t replaces the 317 (pos)
These work great in the power supply. I also got the biggest heat sinks that will fit in the box (external)

Used a little thermal grease just in case.
As for the wiring I noticed a couple things that were incorrect. If you wire the volume pots like the manual they will behave backwards. Also be sure to wire the wiper to the mute switch and make sure you are grounding the pcb side when the mute is engaged. Otherwise you're sending the output of the op amp to ground and they get hot fast (personal experience, fortunately didn't fry any)
Also I had to wire my signal leds the opposite of the manual. I don't know if this is a variation in the leds or an error in the manual.
Hope this helps. Mine has been up and running great for almost a year now. Totally love it. Feel free to pm me if you have other questions.
