Musical Fidelity Clone

[engineman]

Recently purchased PCB's that are based on the Musical Fidelity A2 class A mosfet amplifier. No documentation was sent with them and none was found on the internet. TransLAB is the silkscreen name on the boards. I have begun to buy and install components and would like to find support and discussion on the design. Has anyone attempted this amp project? I will post some pictures for all to view.

Now that the weather is cooling and indoor projects ready to continue. All components have arrived and will be installed. I will post as progress moves forward.

any progress?

Just curious how the A2 is going?

I am considering this project or a lateral mosfet design like this one. Let us know what progress you have made.

 

[engineman]

Current progress. So much to do!

AF2 Mosfet Amplifer

This is another project where 7 of these amplifiers are assembled. They are lateral mosfet AB design. Sound quality is good. A better source material is needed to really hear the sonic purity of the design.

Thanks for sharing that.

I have been interested in these amplifiers for some time now. How did those translab boards work out for you? Have you tried them? Are they worth buying or should I look somewhere else? Can you rate sound quality over some of the other common mosfets such as the 5200/1943 chips?

5200 and 1943 are bipolar transistors. When Translab are done they will be tested.
