Hello Everyone,

Does anyone have any idea why a Tascam 488 MKII's mixer would stop conveying the signal to the headphones?
I can see the recording indicators light up on each track but can barley hear anything when trying to monitor via headphones.
Even if the volume is cranked up all of the way...hardly anything is audible.

The machine has been taken apart 5 or 6 times already.
And I see no signs of any visible damage to the components or connections.

Any help or suggestions would be greatly appreciated.

Thank You
