Lowering the output impdance of the TSSA V1.6

If it is required get more grip of the speaker, the following can be done:

Make the Errata note with 470R between Q13 and Q14 and between Q12 and Q15
R7 and R8 changed to 2K
change R22to 500R.
Do a new trim.

Trim to 500mA idle. As this gives the best distortion.

Distortion into 4W 8R is now 0.068% into 1KHz instead of 0.137%

Zout is now 0.28Ohm instead of 0.35Ohm.

The peak idle current at start up rises to 1Amp shortly for a few seconds. After 5 min it has settled to 500mA.
