Tweaking a solid state amp would be much more difficult than a tube amp. Tube amps usually have more room to work in and are generally much simpler circuits. Solid state amps on circuit boards would be more difficult.
One great benefit is getting rid of electrolytic caps and replacing with oil/film or other film caps but the sizes required in a solid state amp would generally be so physically large that getting them in the chassis would be a problem.
Of course tube amps are a bit more dangerous with higher voltages.
Get some books on basic electronics. Prowl around over at Audio Asylum in the Tube DIY forum or other DIY sites. Google "DIY audio" for a lot of good sites. Maybe take a few classes at a local technical school or community college. There are a lot of sources with ideas for working on tube amps that are geared toward guitar amps but the principles are the same.
good luck
