QUAD 44 Amplifier Repair
This amplifier came in with the report of low output on the Left Channel. Tests confirmed this and after a lot of searching I managed to find the correct circuit diagrem for it, there being quite a number of variations and modifications during production.
I traced the fault to the switching betreen MONO and BALANCE and then discovered a loose connection. Actually, it was visible much earlier, I just didn't see it.
Reconnecting the loose resistor restored normal operation
