[Elecraft] K2 : troubles with level on AF speaker

[Cyrille DERORY]

I'm Cyrille DERORY, a french who is living near the city of Brest.

This is my first K2 (serial 4542) with optionals : SSB, 160m, KIO. The 
AF sound is ok with headphones connected on the front panel. However 
without headphones, the audio signal is very low AF power on the 
internel speaker or on the jack for the external speaker. After 
verifications, all components for the audio part are in the right position :

on the control board : R16 .....R20, C23 .....C30, Q6 and Q7
on the RF board : R35, R36, C105, C106

I've even tried to change the speaker but the AF signal is still very 
low power.

AF gain R3 is working.

Any idea ?

Thanks in advance.

Cyrille.
