Hi,
The EPS P3A amp seems like a quite nice project to feed the lower end in my upcoming biamped speakers with.
Since I have some serious hardware piled up (750VA 2x24V transformer, several 66500uF caps and four big heatsinks) I´d like to beef it up a bit.
The suggested output transistors seems unavailable here, but I think three pairs of TIP35/36 or BD249/250 would be good enough, huh?
Ideally I would like a pure class A amp, but the heatsinks are a little too small to support that at this highish transformer voltage.
How does the P3A perform at higher bias currents, maybe 1,5A per channel? Would quiescent qurrent stability be a problem? |

| Yup, I´ve seen the P3B. Maybe that´s more what I´m looking for, though I´d still have to add extra output transistors to deal with the dissipated power |

hi Fuling,
it's simple to add one more pair output transistors and you have all informations on ESP site.
Ask Rod for details he will help you.
All the best! |

| If you are really interested in running Class A, which is known for running hot, why don't you use 4 or more pairs of transistors, to better distribute the heat on the heatsinks. |
