Seek Class AB PWD AMP +/- 80VDC Regulated Supply

[ckwong99]

Hello there ,

Can anyone share me regulated power amp class AB supply schematic or PCB layout ? I try to make the AMP about 150Wx2 .

Also attached schematic but it is only support 45VDC +/- , can anyone know how to modify it can support 80VDC ?

Audio Amateur magazine published plans for power amp regulators in the 1/1980 issue, by James Boak. I may still have that issue, or a photocopy, though all I found just now was a single page. If you search diyaudio for boak you'll find some discussions, ike this one: http://www.diyaudio.com/forums/solid-state/13261-boak-power-supply.html
