What a waste of money! All the hype for this book lead me to believe this was a book that would be valuable to a beginner in the restoration of antique radios. I should have ignored the positive posts that were obviously posted by close members of the author's immediate family. If one is into theory, this is probably about as good as it gets. If one is looking for basic restoration help, fugeddabowdit!
