I've seen observations that some audio power amplifier can be made to
work by removing any circuitry to limit their bandwidth. Audio
amplifiers generally have high linearity within the audio spectrum, but
depending on the devices used and the feedback networks, might not be so
good at 630M, and efficiency of the output devices are likely to be
lower. I own several, left over from my work in pro audio. One of these
days I should look into that. :)
