Les	Re: bass/treble control not working the bridged-T in this application looks like this: a pair of resistors in series, this pair is paralled by a cap. at the junction of the pair of resistors, there is a cap that goes to ground. the values are: Rpair=220K, Cparallel=330p, Cgrnd=.0047u. I'm at work so i don't have the schematic handy to post a pic, but can tell you this, on the Minuteman, these bridged-T's were hun off the center lug of the volume controls, the cap to ground was grounded at the input jacks, and the other end went to the eyelet board. hope this makes sense...
