Reminds me of the market for tubes for guitar amplifiers. The "good" tubes are JAN (Joint Army Navy) tubes which were last produced in the 1960s. Someone must have acquired quite a cache of them because they are still turning up albeit at increasingly steep prices.
- johnr2 6y ago> The "good" tubes are JAN (Joint Army Navy) tubes which were last produced in the 1960s. s/1960s/1980s Sylvania was still making them up to 1981, when Philips ECG bought the Sylvania tube factory so they could supply the US military. They continued making JAN tubes until 1988. A lot of these are still available.
