I've just completed a service on a Clarke & Smith 959 schools radio. This has a D&W FM
front end, with the output fed to a Mullard module. By replacing a couple of ceramic
caps with high quality trimmers I have extended the band to 108 MHz for which I will
make a replacement FM tuning scale. I was surprised the local oscillator was 10.7 MHz
low of the signal frequency. Performance is excellent.
