There is at least one problem with the 30+30w amp on the Talking Electronics website; the MICRO PC input is tied to +6v. Not good.

For your 50w amp, take a look at Rod Elliott's site:

The Articles section has a number of articles that directly relate to your inquiry.
Here's one from the Beginners section about troubleshooting preamps, amplifiers, etc:

i hope you get your project going! ive built a guitar amp, distortion box, and a wah wah pedal. fun and challenging. the thing i like about about finding a guitar circuit is modifying the components to make it sound the way you like it. good luck!

There are several designs for high power stereo amps in the completed projects forum. Do a search for cumesoftware (his user name). Some are on the front page.

Here is a website for schematics for Fender, Peavey, Marshall, etc... along with wiring diagrams for guitars.
