Music Fidelity A1

Stormrider · 29th June 2008, 08:39 PM

Anybody ever cloned an A1? The circuit is simple with cheap/available parts. Supposedly it puts out about 8w in class and then up to 35w in AB making it an A+AB correct? Any PCB designs around?

You could always design your own PCB ?

There are plenty of free packages around.

Or try ebay.

I think there are some much better circuits around than this.

Do a search on the forum and you will find a lot of good amplifiers you can build - class A and AB

Yes, i saw the kit on ebay and thats what prompted my post. I did find another thread here on diyaudio and someone there made there own PCB but it seems to be based on a different version of the A1.

Whats wrong with this design Bonsai?

Where did you find the PCB on the forum?
Is there a link to download?

Does anybody have a schematic for the A3CR? I would be curious to know what the topology looks like. I had a chance to have a look under the hood of a friends amp, but I was a bit short of time and it would have been quite some work to get access to the track side of the PCB, so I never had a chance to reverse engineer it.
