Does anyone know of any DIY solid state amps that are of easy to intermediate difficulty and are <$200? I have had my SSMH for a while now and am looking for something new and not involving tubes.... The Beta 22 is too complicated and simpler designs all seem to be sub-$70 portable amps.

CK2III.

CKK-III, PPAv2 (more difficult), M^3. If As most of your headphones are low-impedance, consider a buffer as well, such as the SHA or Szekeres.

m³

M3 would be my choice as well. Instead of rolling tubes, you can roll opamps.

Thanks guys, I think I'll probably go for the CK2III

The CK2III is a good choice because the power supply is on the board - that makes construction slightly easier. It is a very good sounding amp, as well.

A dark horse might be the Dynalo. There are some issues with chip availability, but you might want to check Dan for board and substitute chip availability.

Found a discrete amp here - tom.5u.com/files

Shouldn't be any problem about transistors for the Dynalo. The 2Sk170/2Sj74 are available from amb and Beezar and the 2SA1015 and 2SC1815 are available from from MCM Electronics.
