Hi gang,
My reading for Q7 base is too low, but not shorted.
I get 760 ohm...
But I should get 2.5 to 3 k ohm.
I have worked my way through the schematics.
At R62 I get zero one one side and 870 on the other.
At R60 I get 870 and 760.
The low resistance must be somwhere between R60 and Q7 base.
I have removed all passive components that connects to ground: C137,
C129, C130, C138.
No change.
I don't think any of the T's are shorted, cos I dont see zero ohms.
Please give me some hints if you can, on how I can proceed.
Tnx
