An old Class A power amp design that works surprisingly well for guitar. Power isn't very high and you will need a huge heatsink and/or a fan. But, the basic circuit only has four transistors.

Kevin O'Connor's TUT2 book has a chapter on solid state power amps. You can basically roll your own by matching a front end to various power stages. Lots of other info on tube amps and tube/transistor hybrids.
