Here's some "long shots" for SHS parts:
Sidetracks.net in Colorado had some SW9 boards but Tom H. is selling the business lock-stock-and barrel. So to get one you'd need to buy the whole business and I don't know if SW9 boards are inter-changeable or not, likely not.
At one time Dallee indicated they could repair a loco-matic board for me. They might be able to repair a regular AC-DC board. Albeit at an expense $$.... It might be cheaper to buy a used SW8 somewhere.... I've got a couple (I think) one has a locomatic board in it and one is AC/DC. Doug Peck had some SW8's in his stock at one time.
If you haven't already, check out the SHS Yahoo group and pose the questions. Don T. "lurks" there and responds. At one point Don could quote "chapter and verse" which part was in which box that he shipped off to Clay and company. And I think I recall a response from Clay with "new" contact information. But it sounds like you've got that already and it's just a case of his timely response.
I "know" of people who have converted their SHS to DCC and I've "lucked" out and bought their Loco-matic boards that were gathering dust. Again multi-post at the Yahoo groups and someone might respond.
Good luck,
Bill, Kelso, WA
