As per usual, Peterson and co. helped me out on a recent kit build. I messed a few things up and could not calibrate my 73P 500 kit properly. The videos on the site were super helpful, but this is generally where I struggle with other builds; the calibration/measurement aspect of things.
When I realized they offered this service, it felt like a no-brainer. Easy to ship off and got it back in no time. The only suggestion I would make is to leave a note or send a video on what was actually fixed/repaired. I've built over 30 DIY kits and have had a pretty high success rate, overall. When I've run into issues, I've used Trace Audio, great guys btw, and a local guy in Chicago to help resolve issues. I realize this is essentially a "no cost" solution/loss leader, but at the end of the day, I want to know what I did wrong, so I can learn from that. That's just me, though.
Anyway, great kits, I love what you do for the DIY community and keep making kick ass gear!
