That sounds interesting John. I've just discovered that the 3/10 Compton I grew up on is now less than 10 miles from me in a private residence. It needs some work but once done, I'll be able to play it once again. It will be interesting to compare the stop list. Those 10 ranks sound familiar but it was in the mid to late 70's when last played it. What you now need is the electrostatic Melotone unit!
