I'm surprised a reputable company like DXE would sell the brand: https://www.dxengineering.com/search/department/amplifiers/brand/rm-italy/product-line/rm-italy-la-250-series-vhf-linear-amplifiers?autoview=SKU&sortby=Default&sortorder=Ascending

It's quite normal for power amps to generate strong harmonics -- 5dB down is common for the second harmonic -- so they must be filtered by an output network. Solid state amps without tuners have networks that match to 50 ohms. Tube amps use either Pi or Pi-L networks that are tunable. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
