Hi.
I want to build a practice amp. so I started searching for amp designs.
The first thing I found was Marshal MG10. which I don't really like that much and because of resistors range I might end up buying lots of spare parts. (about 1500 resistors that I may not use any time soon).
then I came across this Rickenbacker TR7 that is transistor-based  (I enjoy working with transistors more <3) ).

Rickenbacker TR7 preamp and power amp schematics:
http://www.rickenbacker.com/pdfs/19340.pdf
in the TR7 power amp, there is an MFC8020 that I think it's impossible to find. (couldn't find any substitute either).
what do you think I should do about the power amp in TR7?
do you recommend any other simple transistor-based amp design?

thanks
