I'm doing the exact same to my Roland PA-250, including new faders, power amp revision and new mahogany side panels to get back to regular service after 25 years out of service. It's a beauty! I hope your PA-250 performs well and always does the job you need, when you need it. Good luck for you, Nick. Mine is almost done. Macedo Pinto Portugal
@@NickHabermehl I didn't even think about it when I started working on the Roland PA-250 and only took half a dozen technical shots to keep track. In fact, the happiness of working on this Roland made me forget about the rest of the world, Nick. Typical of a guy who only really cares about electroacoustics, I see now! My fault! But you're right. I should have filmed this. Next time, I'll do it! That's for sure! Cheers!
BTW... Tell me something…: You're not planning to take advantage of the Roland PA-250 for microphones, are you? If so, good for you. In your case, I think you will use it mostly for Line or Instrument Level. In fact, using this desk with low-impedance microphones is problematic. And I really need microphone inputs. The input impedance of each channel of this mixer is 10KΩ. Those are "mid" impedance inputs. Therefore, it is not "Mic" nor "Line" impedances. So you need to have a bridging impedance process in order to work correctly. To connect low impedance microphones (such as the Shure SM 58 or SM 57 it is necessary to use a microphone transformer before each input channel. Something like 75 $ in each transformer, which makes this kid have expensive habits!

You should film your process and upload it to UA-cam. I’d love too see it!
