Well. I got my 8010 up and running. The Ebay ON transistors were counterfeit. I bought replacements from mouser. I also found a spare driver board. Put it all together, powered it up on the DBT, and all is fine. Pete's advice about buying known genuine parts is the most important lesson in all of this. Someday, when I get brave, I'll try to troubleshoot and repair the bad driver board. I put it in briefly on the DBT, and everything was popping once again, but that wasn't a surprise. I repaired it with Ebay parts I had bought on the first "go round".
