Quite a few of us started out by repairing our old Leak Stereo 20s and
the like. It's still a great road into amp building. for a first step
I'd do exactly that - buy a Leak Stereo 20 and upgrade it with modern
componants. It's all point to point wiring and totally accessible.
Plus you have the leak group as backing to talk you through it. Morgan
Jones even has a suggested circuit for it in his Valve Amplifiers,
which you absolutely must buy. (that's an order!!!)
I think to date I've been through about 30 different circuits in my
Leak Stereo 20!!!
Agreed Andy. A Leak Stereo 20 is a good place to start. I
have just finished one of those (actually I was putting it back to
original spec before doing the MJ changes and also those
suggested by my good friend Peter Lewis.
Leaks do have stability problems, and so cannot be claimed
to be unconditionally stable in the true sense of the term. Put
a 0.22µF across the output terminals and watch it dance:-)
But it's a great place to start. and much more informative than
building a kit.
There are plenty of people here, and also on RAT who are happy
to help.
