Exclamation TSSA Basic - bias currents

Hi Gerhard

I recalculated bias currents according to valid configuration as it is now.

Some resistors and multiturn trimmers corrected, please check. Hopefully you are not so far that it is too late to make corrections.

Wish you're enjoying in the workshop
