Here is a link to a thread about amp plans. I posted some as attachments on page 6. I can't member where I got them from and have never tried to build anything with them. I have heard that they will point a person in the right direction. Some tuning of the input and output will probably be needed with the HG transistors as these plans had Toshiba transistors in mind. I was going to build a 4 pill and started trying to buy the stuff. It seemed that there was not a place to get everything from. I think I had it narrowed down to about 3 different places the stuff was coming from. Then I added up the cost of parts and shipping and I was very close to the price of buying one already assembled. The biggest obstacle for me was knowing if there was a problem with the amp before the transistors blew up? How would I know if it was oscillating? The first amplifier maybe should be a little smaller, like a 2 pill on a 10 pill chassis for future expansion maybe.
