Hello AK'ers.
I retored my 2270. SN 38510. BASES ON THE SUPER POST from @Leestereo and recently @Super Noob .
All is fine except LEFT amplifier ( P750, LEFT)
After all the new parts installed, BIAS is about 2.1-2.3 mV, i know it should be 10mV.
I changed diff transistors, pre drivers, drivers, h760, i Installed the resistor recomended here in AK.
Well. Should i reach 10mV ??
2.3 mV is not-too-bad?
