parallel Class AB amp?

well its all original so the components should b the same

thanx haydn

if 1% components have been used than that gives a 2% spread and some could be 10% or worse.
National show 0.1% for some of the parallel schematic resistors.
At low frequencies the caps become part of the gain variation. These too may need to be matched.

All that spread needs to be reigned in with a couple of 0.5R ER's.
