[Boatanchors] AM linear question

[WA5VGO]

I'm not saying it can't work. It can work well. The problem is, most commercial amplifiers don't have the cooling and power supply necessary to do the job, and there is a large group of guys out there that have no idea of what it takes to tune a linear amplifier for AM. The guy running the 811A's was driving it with a B&W 5100B running full tilt. These guys get a 50-100 watt AM rig, hang an SB-200 on the tail end of it, tune for maximum output and let it rip.

Most of the modern 100W SSB rigs when set to AM will automatically limit the carrier to 25 watts, drive your typical well adjusted 10dB linear amplifier such as a pair of 3-500Zs and you have 250 watts of carrier with a potential for 1000+ watts PEP, and a nice clean signal.
