Darryl,
Thanks for reopening the Magister thread. I read Grumpy's post quoted in Ron's letter and remember being impressed by the level of theoretical understanding. However, I didn't recognise that the quote in the letter had come from Grumpy's Outdoorking post. I'd apparently forgotten what the post actually told me! I've reread Grumpy's posts and see that he has given some advice about determining condenser and rectifier values. I would appreciate any further thoughts Grumpy may have on the Magister project.
Regards,
Grant
