Thanks for the help. I got a call back from John Rutan after e-mailing him and he has some info on what is going on. Dean Klienfelter is indeed working currently with Richard Vandersteen on some things but John did not recommend contacting Richard about getting access to Dean right now. John has a similar situation to mine with a PSE amp that is not working. He told me that sometime in the next 6 months or so he was going to make contact with Dean who may be available again by then to repair or at least get us access to schematics perhaps. I will stay in contact with John and hopefully get these working again.
