mxr auto phaser, i need a little help...
« on: February 07, 2007, 03:51:01 PM »
recently put my dirty hands on a mxr auto phaser (blue!) circuit board. I also traced the schematic to make a proper edge connector and try/repair the board.
also my schematic might not be very accurate (the board is double sided!) it shows that this rare piece has 6 stage of phasing through vactrols and could be connected like this:

pin1 : cv out
pin2 : cv in
pin3 : non connected
pin4 : v+ (15V to 25V ?)
pin5 : ground
pin6 : ground
pin7 : phaser out
pin8 : phaser bypassed
pin9 : input 1
pin10: input 2 ?

any information on this ?

this is rack gear from the seventies, those are common in studios but rarely seen on the web...

here are pictures of an autoflanger -> http://www.modezero.com/autoflanger.htm

rusty components testifies how much liquid it sounds !
