As they are very simple to make because of the few components and because I have no clue about Pass Labs and want to learn I wanted to have a go at an F5 amp following Nelson's design:

So what do I use for Q1,Q2,Q3 and Q4? I realise Q3 and Q4 are the output devices, I want to achieve about 50W/ch is this possible and what input voltage would be recommended?

Thanks
Boscoe

While you're at it, also read all the zen variations from passdiy.com

The answers to most of the questions you will have can be found in one or the other zen articles. In fact, the whole zen compilation is a great resource for beginner amp building.... another one of those genius things that Papa has created.
