I've aquired an old Sony PD 150 and PD 170 which I want to pass on for charity use. Alas they don't work and, as a former producer, I know nothing about their insides! Is there anyone who might be interested in fixing one of them. I'd like to take one in February 2012 for use in a deprived area of Cape Town. I'm John Forrest and can be contacted at privatejohn@hotmail.com.
