I have a balanced JT connected to a Beta 22. The volume output between the 2 channels is different. Swapping the outputs confirms that it is an attenuator problem.
When I increase the volume, around 10-12 clicks there are muted increments with no sound. Beyond that it gets loud extremely fast and at a point the volume cuts out and increasing further there is no sound output. The Vac from the power supply is 10 Vac. The volumite appears to be wired correctly. Any ideas?
Thanks in advance.

Is one channel working properly and one misbehaving?
1) It could be misplaced resistors... Check the resistors are the same values in each position on both boards
2) It could also be the ribbon cable or a bad/missing solder joint on either the ribbon cable connector or a relay on the misbehaving board.
I picture is worth a thousand words :)

Well that was embarassing. I went and rechecked everything and found that I reversed the ribbon cable on the I2C Relay Driver  Everything works great now. Thanks for the quick reply Brian.
