I just bought a kit to make my own F-Set, and I am having problems with the probe. Its basicly a 2N5484 FET followed by a bc549 feeding a LM386 amp which detects the signal radiated by a tone generator based on a pair of 555s. Does anyone have or know where I can look at a circuit diagram for a similar product? The kit has only a circuit diagram which does not match the parts or the PCB. Foolishly I assembled it by following the PCB, which may or may not be correct. -- CW. -- http://www.piclist.com#nomail Going offline?
