David Belles still answers emails for power modules usa, although, My experience with him has been terrible... I sent an email asking easy, general questions for amps that he designed. I made sure that I was cordial and brief..... To my surprise, he answered me fairly quickly, it was a simple answer...
"I do not have any current affiliation with these products" I made an appeal and he never responded again.....
Hopefully, You may get a better response than I did.
Good Luck, Tim
