Default What do you recommend

I havent played with FETs from a design aspect properly for donkeys

I like to start in miniature and work my way up

Rather than leap up to doing some stonking great amp - I'm thinking of perhaps trying a FET based Pre-amp with RIAA - Line and other inputs + A FET H'phone out at low rail PD

This way I don't have my eyebrows removed again and end up looking like my avatar

My preference in BJTs at signal level are BC547,549,550,560,557,638, 2N3816,2N3838, - 2SC2705, 2SA1145, ZTX650,750....etc...

Now I have absolutely no idea what are the best small signal FETs would be in such an application...anyone any ideas?

20/10 for attitude, Loopy!

...as opposed to clueless noobs wanting to build a 1000W amp as a first project.

Sorry, can't help with the actual question. Never did quite get the hang of them new-fangled fet things myself.
