Has any body a Class A amp plan, mosfet, high-end. 25 W per chanel aprox.? I Woul like put at the input an 1 V line level? I think woul be a power amp (without preamp). Thanks.
There is also the Lang Class A amp from "Audio Electronics" (formerly known as "The Audio Amateur" when the project appeared. I think their web site still lists the PCB for sale. The TO3 metal case lateral Hitachi MOSFETs are no longer produced though. You could do a little surgery to use some of the TO3P or TO247 plastic package lateral MOSFETs from Hitachi or Toshiba.

Hawk A18 kit?
It's a commercial kit, not a project. A PP 20W class AB amp (10W class A) without loop feedback.
I just had one in for review, and it is indeed a very sweet but powerful and solid performer.

An externally hosted image should be here but it was not working when we last tested it.
The upcoming Zen with an active current source
will reach those levels. Should be out in 3 weeks.

It depends which one(s) you are interested in. There are a number of different Class-A designs on my website ranging from the Hiraga 'Le Monstre' at 4Wrms into 8ohm to Stan Curtis' 60W circuit. I haven't built them all, but can recommend the JLH Class-A which has been highly regarded for the past 30 years and is still generating very favourable comments from new constructors.
