Hi
I’m trying to repair a technics su-v2 amplifier.
On the main board, both stk8040 ((ic301 and 302) and the an6552f (ic303) are faulty => i removed them
I disconnected the source input board from the main board as well (5 pin connector)
Afterwards, i measured voltages :
All power lines are OK but i found that voltage on the ground line (pin D or 4 on the connector between the source input board and the main board) is not zero
Is this normal ? Which value should i find ?
Thanks for your help
