Re: Lafayette HA-350
Hi John, that's brilliant, yes please. You have a P.M. I have run the set up on a step-down transformer and its performance is quite lively on 20m and 40m in the late afternoon. I wait to try the higher frequency bands in the morning. Some time in the past a mod was fitted to the S-meter circuit. According to the schematic the meter is supposed to be driven from the final IF valve cathode (V6). On mine it has a diode connected via a 30pF coupling capacitor to V6 anode that feeds a BC237 transistor and resistor network powered from the heater supply. The meter is controlled by the transistor collector current. It's not working at the moment and so I need to figure out what's going on. I'll do that first and probably revert the circuit to standard, before playing with the alignment, which might be unnecessary. Cheers, Jerry
