Re: Amp Supply LK800 Meter/ALO Board Question

If you do use an attenuator, which I do here for one of my amps, you will have to find a way to bypass it in receive or you will have 3dB attenuation of the receive signal. ?

All- Thank you for the information.? I do not recall having a spectacular failure like that, but perhaps the person I loaned the amp to did.? Regardless, it still appears to be working.? Thank you for your help! Regarding manually tuned gear in an automatic station, I fully agree.? My main amp is an Alpha 9500 for that reason, as the antennas and rig are interfaced, and all switching is done whenever I change band on the radio.? This amplifier is being driven by a Swan 350B, which is manual everything - my first radio?that my father bought me when I was a kid.? That brings me to my next question: The?Swan puts out 50-100W, and I need to detune the driver as the only method?for bringing the power down.? Is there a simple mod that will allow this amplifier to accept more power?? If not, then I will buy a 3 dB attenuator to put between the radio and the amplifier (rated for at least 100 W - they're pretty inexpensive).
