I DO NOT suggest being an authority on this subject about transformers, but in my experience over the years with them, it sounds to me that 30 pounds for a 1.5ACCS transformer is very light weight. S

It is quite a process to accomplish this "piece meal" You need a new bandswitch, wafer, and input wafer as well as a 10 meter input coil. Its a lot of work to do the conversion. The easy way out is t

Tim, if you are getting more idle current than is specified then your zener diode has gone. I don't recall if they use that electronic baising on that amp, but if they do, whatever sets the bias volt

Hi Bill, I once used an MFJ 16010 mini-tuner in front of my Swan Mark 1 amplifier as a tuned input. When not in line the exciter (Yeasu FT-847) would fold back in power to about 50 watts. I would the

TIM, the 120volts for the fan when the amp is plugged in for 240v operation is derived from one leg of the 120 from the wall socket and the neutral is derived from the center tap of the dual primary

Hi Bill, Did you try retuning the coil after you replaced the caps? If you did, maybe the coil material cracked? At any rate, I would try adjusting the coil for least SWR and if that does not work yo
