Murphy Maniac,
I'll re-iterate that my diagram may well contain errors as I've not yet had a chance to thoroughly go over it. It's pretty darn close though. If I can help at all then please drop me a line & I'll see what may be done. I did some other drawings regarding the multiway switch, what gets switched in & out etc. so if you would like them I'll email them over to you. Mine sounds very bassy but muffled at the higher frequencies, just as they used to back then! Plenty of volume as well. My chassis was filthy, black greasy deposit everywhere. Best of luck with yours, keep in touch.
