It's been a few years since I looked at Audio Amp IC's on the LF bands, but I'm now trying to find one that works to some degree at 136kHz.

I need to find an audio IC capable of about 15 Watts as a minimum.

It's for use with a standalone PIC based PSK transmitter that uses the G3PLX Varicode, I just thought that a good IC would minimise the component count.
