[Heath] AR-3 - another question

[Glen Zook]

OK, I took my AR-3 out of the cabinet.  With the 3-turns of the main tuning knob to cover the dial, the planetary drive is working!  It is a 6:1 ratio which means that it takes 3-turns to go 180-degrees.  If it were frozen, then only 1/2-turn would cover the entire dial.  6:1 is a very common ratio for such a drive. 

Not a good ratio for precise tuning but a whole lot better than a 1:1 would be!
