To echo the advice of others, unless you're a skilled tech or know someone close by, I wouldn't touch this amp. The "name brand" amps sold in the US through distributors are well engineered and supported by organizations that will honor warranties and deal with problems. The amp you linked doesn't even have a manual in English (instead referring you to "other amps" manuals). If you need service under or post warranty, you may be on your own, or hit with a big shipping bill. The listing also doesn't say it's been registered with the FCC or meets US spectral purity and gain regs. If there's one place in your station to get a solid piece of equipment and not "cheap out", it's the high power amp. High power needs well designed circuits and robust components to function at its highest potential. It also needs well designed and built safety lockouts - with the high voltage involved you can die if you get inside for any reason (not just installing the transformer). If you don't want to pay the price of a new amp, look at the used market. There are lots of well designed and robust tube amps of recent vintage worth looking at that won't break your bank account. There are also a number of techs around that can work on these amps if not under warranty. Solid amps made by Alpha, command, Acom, and QRO come to mind. Some solid state amps might be ok but full legal limit ones are fewer in number and higher in cost. 73, Lou, W0FK ----- St. Louis, MO -- View this message in context: http://elecraft.365791.n2.nabble.com/OT-Amptec-LA2000-Linear-Amp-tp7618111p7618126.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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
