Put it this way: I have a very early 1960's Philips car radio crammed with AF117's. It works just fine.
However, the other night I read an article online about transistor radio repair (as well as Mark's tips and essay). Well, this guy had his RF stage neatly summarised. It was check the audio stages first and if that's all OK, it will be the AF117's. Remove, test and zap. Put it back in circuit and your radio will be restored. Maybe that is the case. Still what I like about the AF117 is at least you can fix it. I love the sleeved leads as well.
