Greetings all, I am sorry this is off topic but I will keep the noise low. I have just purchased an MFJ-248 Analyzer and I wonder if anyone would have a circuit diagram of this unit. The has been a yellow wire cut off inside going to the top panel I think and I am also looking for the information on the rotary Frequency switch, I think it is a 6 position single pole rotary but I am not sure it is a standard one. Any info would be very welcome. Regards ..... Peter  ZL2BAU
