I bought a pyle PHA40 headphone amp. It appears to be close in size and specs to the Behringer HA400. It powers off the same type of cable used by the KX2/KX3, same voltage and polarity. I paid 16.60 for mine on Amazon.
I connected it to my KX3 and the audio quality sounds good. I didn't detect any extra noise introduced by the amp. 73 Len ______________________________________________________________ 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
