hello gang, been away from head-fi for a while, had other things happening in life.
wonder if you guys made any breakthroughs during my absence?
I basically had to set it aside and wasn't able to work on it for a couple of months.
Just a few minutes ago, I finally unscrewed the board from the bottom plate, and immediately noticed there were exactly three spots were traces were cut.
When I say 'cut', I mean literally cut as if it was done intentionally with an exacto knife. There isn't anything that comes to mind that might have caused such precise cuts when I didn't even separate the board from the case up until now.
Could this be a part of the original design / abrupt design changes that were meant to be there? If not, i guess my best bet is getting a hold of some conductive pen tomorrow.
Let me try to take some pics with my phone
Here it is
Now that I think about it, I think the mods went in this order
Output caps -> DIR9001 -> Resistors / Input caps
It was after the output caps mod that I lost the one of the channels (but wasn't aware, as the outputs were shorted and I was hearing dual mono from there on
). Must have been the easiest mod, can't imagine something going wrong there. I was gonna ask if a failed DIR9001 mod could mute one of the channels, but I guess it was happening before I mucked with DIR9001.
