Yes, I did. I´m using his DOAs in my Don Classics 250. They are spot on. That combination is as close as you can get to a real 250c. I had them side by side. Joe´s DOAs are available with 2520 pinout, so he´s doing us DIYers a big favor.
Joe´s DOA came out when I was in the middle of reversing the HS2030. I don´t know if I´d done all that work if they were available earlier. Anyway, his DOAs are SMD and my version is all original THT with all those obsolete unobtainum transistors. As I said before I repair Sontec, mostly for mastering studios here in EU, and most clients want it to be as original as possible. That´s what I was trying to accomplish with my PCB. From a commercial POV it doesn´t make sense to do it other than SMD. But paranoid mastering guys love that minute detail ;-)
