Hi all, I’m trying to adjust the no signal current on a Beomaster 1100

I have downloaded the manual for BM1100 and BC1800. I would have thought to adjust the trimmers (R155/ R255)to give a output of 10mv across resistors (R159) and (R259)as this seems like the logical steps

However on Beocenter 1800/BM1100 manual it says to adjust (R155/ R255) to 10mv across (2tp104/ 2tp204)

Although (2tp104)seems to be jumper wire and (2tp204)is obscured with another rectangular component.

Any advice most welcome

Hi,

In the service manual I have it says to measure across emitter resistor 5R113.
