[sdiy] Mackie Mod

[Moho Disco]

Nobody can help me here?... I know, sorry it's OT...  but I just
need one of you people who is much smarter than me to say
something like "Lava, it'll work, put the wire pre-resistor".

Harry, Paul?  Anybody who has been so unfortunate as to offer
me a helping hand in the past?

Help a brother out, I'll send a virtual-beer your way...
