RE: Anyone remember Ed Billeci and his DIY 212 SE amps?.

Posted by Tre' on October 20, 2020 at 19:53:24:
I sold a pair of 308Bs to a guy for his DIY 212 SE amps. He loved them.
"The 308B triode is quite similar to the 212's. The u of 308B is 8 and the u of 212 is 16, this affects the characteristics by making the 308B slightly more linear that 212 and making the bias Voltage for 308B higher.( More Voltage swing is needed )"
