Marco	Re: SLO 100 clone bleeding channels problem Joe!!!, and Steve: I've verifyed PCB layout in my yamaha t100: the clean signal trace to V3 is completly surrounded (a sort of "Aliens" scene) from plate resistors, cathode resistors and decoupling caps from V2a/V2b (lead tube). The simpler solutions I think is not to use the "clean" trace (between 120pF/2.2M and 220K) in PCB and substitute it with a wire separated from PCB (at what a distance, and shielded or not?). This is not a very neat solution, but the T100 PCB layout is not neat at all... Another solutions: substitute new V2 resistors and caps soldered at 1/2 inch from the PCB. Not so neat, eh? What you think? About clean channel's bleeding: can I add a simple LDR in series to V3? Some impedance or level problem? Sorry for my english (it is as good as my amp). And many thanks.
