Rhodes Chroma Polaris

Paul, the reason 5 isn't tuning is still a mystery. I swapped all the chips.  No result.  However the reading I was getting... that was on the wrong resistor.  They changed the pattern I see.  The envelope is showing up if I get it on the right resistor :-).  It looked like a clear pattern but for some reason on 5 they changed it! I couldn't see the writing... anyway I figured probably the hard wired leg 4053 chip but no dice.  Still doesn't tune until I turn it on..then..I find out ..it's tuned.  Whaaaaatever.  I dunno.  I need to see the code i guess to know what routine it goes through on the tuning.  lol
