I picked this one up and gave it a little cleanup and care, looking to turn it around. It is the first version and the QC sticker is dated '84. I socketed the MN3005, and used it to verify a bunch of MN3005's and 3008's I have picked up recently. Works good, looks good too. I put in a Lumberg style DC jack, regular center pin negative, to make it more pedalboard friendly. I'm not a big fan of the 1/8" positive tip power jack DOD pedals come with. When I did this I took out the battery strap so the battery compartment could house a double delay daughterboard, and I have one set up for MN3008's that I was able to get sounding pretty good in place of a single MN3005 with a variety of the 3008's I have on hand. It has the battery door, and the pots are good too. Not easy to find long pin W100k knurled shaft replacements like these use. I'm thinking $90/shipped in the US, or $50 without the MN3005.
