Dave, LM384 works well at 136kHz (5W out) and the datasheet gives a BW of 450kHz for 2W in 8 Ohm. Two of them in push-pull might give close to 5W if you accept some distorsion. And they are cheap (less than 2 Euro) 73, Rik ON7YD ________________________________________ Van: [email protected] [[email protected]] namens Dave Brown [[email protected]] Verzonden: woensdag 21 juli 2010 12:58 Aan: [email protected] Onderwerp: LF: audio amps for LF driver service I've seen comments here from time to time about various audio power amps being used for low power tx purposes - any suggestions as to whats a useful one for 136 up to 500 kHz at the 5 watt level or thereabouts? 73 Dave, ZL3FJ |
