It's a nice amp. You'll like it.   I taped it in 1980
or so.  Just like everyone else, I made subtle
A couple notable ones: metal film resistors where
possible.  10 turn pot for bias adjustment.  I added
audio ramping and thump supression as well.

The power supply makes a big difference in the sound. 
I used a 20 AMP constant voltage transformer and the
AMP sounded great and the hum was horrible.  I then
changed to a somewhat under rated quad custom made
torroidal transformer and the AMP was quieter, but not
as bassey.

I accidently mad a mirror image of the board and
because the design is so symmetric, I was able to use
it with a few external changes and switching the NPN
and PNP transistor positions.

Go for it.
