Winfried Knobloch "Röhrentechnik ganz modern" among others used by the holder of a famous German company for some kind of audio tube equipment, that is used by all famous recording studios, all over this planet. People from Germany interested in developing tube equipment, should take a look at this book. Tubes aren't dead, but some, especially very small tubes aren't available today, only from storage from the past, but this also happened with the grandios CEM/Curtis ICs. Yes, a well known man let produce those ICs for his company, but they aren't available on the marked, if you want to repair old audio equipment using those ICs. Even ICs die out and tubes are still used for brand new developed professional audio equipment. OTHO a lot of amateur audio equipment based on tubes is less good, than a discrete transistor based circuit. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
