Very nice new old stock, original box, Siemens C3m German made tubes. C3m is a long life, low noise "universal" audio or RF signal pentode. The C3m also features a 10,000 hour life rating by the manufacturer, about 5 times that of typical consumer tubes, so in normal (10-20 hours per week) use would last 5 to 10 years.
