As I have posted before, M. Mardis is presently tearing apart my Little Dot T-100 amp (awful name!). I appears that the tube front end is a botched add-on that may represent more work than it's worth to get right. I was thinking that since it has its own power supply already and circuitry it might be possible to replace with a nice built in DAC. I have already put this to M. but would appreciate your input. pics
