Re: [motm] Re: No penguins = MOTM-485 mods

2005-08-07 by Richard Brewster

I noticed something odd about Dave's assembly photo of the 485.  If the 
jacks are labelled like they are in the catalog photo:  Left side top to 
bottom:  IN1, IN2, RES; right side top to bottom:  1V/OCT, FM, OUT, then 
the jacks are not wired correctly.  The photo show IN2 as wired to the 
top, right jack, and a twisted pair to the middle left jack.  
Accidentally reversed?
