Wondering if anyone has a suggestion of a solid state amp or "pushing" the K3 PA to obtain 150 watts out on 160m? A kit or HB would be fine... 73, Julius n2wn The only reason known to ask for such power increase will be to excite a power amplifier using 3-500Z or similar to full legal output. A Henry 3KA with 100 watts drive under the best of circumstances will not deliver more 1200 watts. On the other hand, new amplifiers with ceramic tubes like 3CX1500A7 or Alpha 87 with 3CX800A7 will deliver 1500 watts with only 45-50 watts drive. The Expert 1KA Italian amplifier with solid state finals needs only 20 watts drive for 1000 watts out. In fact, you must be very careful not to overdrive those amplifiers 73 ______________________________________________________________ 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
