I am getting ready to build the 200W version of this amp this year - hopefully. I have two questions:
1. What current gain group would you recommend for the BD139/140 BJTs - 10 or 16?
2. What are your thoughts about using a switching power supply with the amp - something like Hypex SMPS1200A700 (63Vdc 100 kHz switching frequency)

I do not have intetion to offer any more PCbs for this amp, but here are gerbers for 200W CFA board, balance addin board and PS regulator board.
Have a nice time building and enjoy listening this powerful amplifier.![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
