It has really low, distorted output, even through the headphone section. Where would a rookie like me, start diagnosing? I've already checked the circuit boards for open joints. Thanks! |

Not to be mean, but if you have to ask...
Unless you are well versed with this type of circuit repair, it really needs to go go to a tech; not sure if there are any Yamaha proprietary devices in thsi pre.
You may find that it will be cheaper to find a used working unit as the repairs could cost more than a replacement.
BTW, in my experience these things are built like tanks; rare that they fail IME.
John K on this board had one for sale that was mint; might be worth using the search feature in the Amp section to see if it is still available. |

Usually, in a case like this, there is just something set wrong. There is no power section to fail and you are getting signal through.

If it's not cables, input jack, or just a really dirty pot- I would take it to a tech to get it checked out. |
