Bray - I only know the broad outlines from observations and a few conversations. The SW1 came out in 1997 from work Jim had been doing for about 5 years. That was early Class D and incorporated thermistor compensation and shaping circuitry ; the SW1 (2-10") were made in-house. That product became the SS2 in 2004, also made in-house with the 1,2,3,4 line. The unique design required in-house repair, which Jim performed due to his intimate knowledge of the complex circuitry. Jim was sick for a few years before he died in 2009. Sometime in there Bash/Canada began producing the amps, but it seems there was continual struggle to keep the sophisticated particulars in-tact and supported. When New Thiel took over in 2012, they decided to cease support of the line, by then out of warranty (red flag.) My speculation is that manufacture ceased somewhere between 2009 and 2012. I don't have direct knowledge and I don't want to bother Rob with my learning curve. I am gradually assembling my fact base.
