[sdiy] MN3207 and MN3102 Reissues

Gregg (and list),
 Built a modified-clone of the Dimension-"C" last year ( and I believe
 another list member has built a Dimension "D") ... sounds very 
 nice...note
 that the circuit uses NE570 companders for noise reduction... and it
 certainly needs them... which is no surprise for BBD's. The MN3207 was
 used in many commercially available fx units.. it is a lower voltage
 unit than the MN3007 and has slightly worse noise specs. BBD circuits
 are a very popular topic on some of the guitar fx newlists, and there  
 is lots of info around. There are also a number of inexpensive digital 
 delay chips  available nowadays that <may> provide cleaner sound with a 
 simpler  circuit.
