Following my forray into resurecting a classic amp (see here), I've got a few designs to share.
Class AB amplifier. It's a re-take on ESP Sounds Project 3A but with a few different components, based around the MJL3281/MJL1302 matched-pair transistors from OnSemi. Built for surface-mount components, it keeps the circuit neat and inductances down. All perfectly hand-solderable.
Should be good for 100W easily - 200W depending on heatsinking. Designed around a +/-30V supply, but this can be pushed to +/-40V.
The sound quality is, quite frankly, amazing. See the attached schematic.
Schematic is attached, along with Bill Of Materials.
If anyone wants to give this a go, I've got plenty of spare PCBs and enough components to kit a few boards worth. Let me know and I'll send more details. UK based.
