RSGB's magazine RadCom of January 2003 features the first part of an article by David Bowman, G0MRF, with title "A Class-D Transmitter for 136kHz".

As far as I can judge it is the same design as found in The low frequency experimenter's handbook by Peter, G3LDO, which has a picture of the amplifier on its cover.
But an article in two parts in RadCom obviously has more room for details.
