Zen Mod:
You're correct, of course. I just thought it might be fun to try something a little different. The idea I'm playing with is to also add a B1 to make this project into a small integrated amp.

something like a DIY INT60 ?
chrisb:
Yup, sorta. One of my daughters is living in NYC and could use a stereo, and I'm looking for an excuse to build something. She's in no rush (which is good) and whatever I build should be relatively low-powered. This might be a summer project. I thought a souped-up ACA would be fun.
ZM:
Yeah, I'll start going back over the thread. My plan is to build something with an internal power supply (probably with a 24V rail) instead of using a brick, and it's been a while since I read the entire thread for ideas/insights.
Jim:
Uhm, a dumb question: would a bridged version of the ACA require different MOSFETs? In other words, wouldn't the polarity of the circuit have to be reversed on one of the pcbs?

Bridge will give you twice the voltage swing which is roughly 4x the power, so about 20w.
I have 2 of these underway to use as mono-bloke. As well i will be bi-amping with a 150w Sears/Hitachi dual mono MosFet amp to drive rthe woofers below 180Hz. Should be plenty of power for my needs.

Mono-bloke.
One-friend.
Get it?

Of course there's an interest in a circuit like that... Fine me somebody to design it and we'll talk!
Rumour has it you know a guy who knows a guy, but he can be picky about his projects
Some guys, really.
Forgot to install them since the pre-production kit I had didn't have any. I'll re-photograph when I get a chance.
Use them.
Thanks Jim! Great work!
The single-ended output impedance is so large. Why do so many people like it?
Low output impedance does not automatically mean good amplifier sound. There are many other parameters that make an amplifier sound wonderful.

Is this a case of judging an amplifier by reading paper specs
rather that actually listening to it?
