Why the heck not? People I know runing G2DAF
amps do sound much better and also have less
bandwith then big time prominent hall of fame
contesters using Alpha/Ameritron amps and
latest so called state of the art exciters.
Whats wrong here? You tell me! Not that I don´t
already know where the problem is but still.
Don´t mock the fellows runing the DAF´s correctly
instead moch the creatures that can´t handle their
fancy equipment and do make life miserable for
others on the band .
