@rbmaudio1 Counterpoint gear is not nearly as hard to service as urban myth has it and there is no need to "rebuild" with new boards all the time. I have 2 of each of the popular models (SA100, SA20, NPS200, and NPS400) and I service them myself. All the old SA'sI have I purchase them in junk condition and replace the mosfets and they sing. While every otherexpert will say they need a rebuild or trash them, it is possible to use new production Vishay TO247 Hexfets in them and those output devices are very cheap unlike the mythical Exicons.
The preamps are real easy to deal with even the SA5000 (not the SA11 though).
