We are experiencing a significant volume loss in channel 2.  We normally run the amp in stereo.  We switched to bridge mode and the output for both channels is equal so we're guessing the input for channel 2 is damaged or something.  We own two of these units and fear that we may have the same problem in the second unit, but to a lesser degree.  Any thoughts for troubleshooting?

If this is only happening in one channel, it is possible that the input connector is dirty, damaged or worked loose. You might want to check the solder integrity on the input connectors and the ribbon cable connection.

What about repair, if necessary.  Will I need to find a receipt.  That might be tough.  I know the amp is less than three years old.  What's your advice?

Usually not as we will go by the manufacturing date code if there is no receipt available for the date of purchase. This is the four digit number on the serial number sticker that will look something like "0014". The middle two digits ar the month and the out two digits are the year of manufacture. In the examples case that would be January of 2004. smile.gif

Since we have two identical (amp) models, we switched the input modules and to our ears, we could replicate the sound degradation of each amp, to the other.

I have two CE2000's, I think the input modules are the same as the UltraTech's.  Are they compatible to the UltraTech's and could I run a test with that module?

They are pretty much the same amp except for color and label. The UTs are only sold through one dealer. So the input cards should be interchangeable.
