I've known Molly and Gordon Hardman for some time, as well as Michael 
Seedman, CEO of RF Concepts.  It was my understanding that much of the 
work on Alpha amps under RF Concepts was done by a contract manufacturer 
in Colorado, very close to the RF Concepts facility.  If not the amps in 
"toto" so to speak, but at the very least, all of the SMD and PCB work.

BTW... Remember Practical Peripherals (the PC telco modem company)?  
Michael Seedman was founder and president.  Later, he was a major player 
in USRobotics/3COM.
