Re: Official Schematics and Manuals Thread (Registered Users)
In addition, Is it normal that the C33-C40 "all 10000uF 80V" boils up in the top in the ET250S ?????. I wondered that there are used capasitors from 1995 which today are 22 years old and after the book is not good anymore .....

Re: Official Schematics and Manuals Thread (Registered Users)
Hi thanks - my name is Jan
I need the bias value because after repairing of a broken broken power amp transistor on the right side. After repair I must readjust the bias. I like to know the value mV/mA and where the measure points are
Best regards
