I have an issue with my old Legato 1.0.3, I powered with +-12VDC but when I want to adjust to 0 VDC with PWR2 the input + channel Left (hot) can't go lower -2.8 VDC with the trimmer, the input - channel Left (cold) measures 0 VDC in all positions?

Sounds like it may be a dead transistor...

Sorry, I get tons and tons of email every day. It's not the best way to reach me. PMs here are generally better.
