Thank you very much, John, for your spiel ref. the XH. I have always thought of the XH as being ¡°different¡±. Anyway, it does not solve our problem, but now we know that we need to talk to a different person. Own up, please, the Designer of the XH, we won¡¯t send you to a nuclear gulag this time!!! And, I do know that other series of 931¡¯s also gave PA trouble a generous outing.
