Hum is definitely there with no inputs connected. I usually use the optical.
DAC repair/troubleshooting in New England
I purchased a DAC in Taiwan quite a few years ago. It’s a dual TDA1541A, with a tube output stage. Really nice construction and components. Pictures are linked below.
It’s always had a significant hum. I love this DAC and would really like to get rid of the hum, but not savvy enough troubleshoot myself.
Anyone know a good place within reasonable driving distance from Central CT that would be capable of this?
TIA.
