On the main wiki page for the MB-6582 (http://www.midibox.org/dokuwiki/doku.php?id=wilba_mb_6582&s[]=mb&s[]=6582) it says I need to solder some wires in order for the passive headphone output to work. But in looking at the schematics and the board, I see tracks running after each resistor to the next resistor and to the headphone jack header.
So I’m a bit confused 
Do I need to solder wires then and if so, where exactly?
Nevermind - I just noticed that the tracks are there for the SmashTV version of the MB-6852 mainboard (which I have) but not on the original V1 prototype board.
So did you have to solder anything, or is J7 0 ready to go? I was just reading up on this very topic.
Hehe, nevermind should be banned on here!
There will always be people wondering the same thing,
that will mind to see the solution! 
Nevermind, I got it 
A quick test showed me that, yes, J70 is all wired up and outputs sound without any extra soldering.
I often wonder whether it’s worth making different revisions of PCBs (and fixing past stuff-ups) or just be consistent. :rolleyes:
