Did you find a circuit diagram or a manual ? I have a Sony CRF 230 where someone put line voltage into the battery socket !!! Sure could use some help rodney_bunt@yahoo.com

Im sorry if this reply is unrelated to your question, and I dont know when it was posted....did you need to live in New Zealand, in mount maunganui? Its just I came across your posting by accident and had a good friend back in the 80's with your name, and there cant be that many people with that name...It would be great to get back in touch , Look forward to your reply.
