Not sure that a Bedini is going to be terribly useful if those Apogees are one's that have the extremely low Z design... it is more or less a function of the size of the PS and the number of output devices that will govern the ability to drive very low Z loads...

I've repaired Strellioff amps, he was Bedini's partner at one time, but I never bothered to fully trace the circuit out.

Nothing special, iirc...

Original spec on 803 was 52 pounds (less than 25kg). There is no way that it could be biased for more than about 10W in pure class A, if that. I think your buddy should look at KMA160 or KMA200, they are proven performers with current hungry Apogees. Even old KSA100 will be vastly better choice.

My aussie 2c (about 0.0001 euro

)

be warned - his aircondition bills will skyrocket ! Good for winter though ...

I just don't want to dispute and - to be frankly - I'm also curious to see that schmtc ..........

Been looking for Bedini schematics for years...

I wouldn't get to much hopes up, but who knows....

I talked with Bedini many years ago and they won't give out the BA-803 schematic. As I understand it. it is a single ended sliding bias class-A is what i was told. I owned a BA-803 and wish i had never given it up! at the time, my speakers just didn't really show off what that amp could do. I had Vandersteen 2c's at the time and while good speakers, that amp deserved better. I have been looking for an 803 for many years now and they are not easy to find.
