Up for sale, an assorted lot of 4 US 1625 cap tubes. Vintage American manufacture 1940-50s. Very similar appearance with large black plates - construction varies. 7 pins, no bad corrosion.
Some people have built very nice amplifiers using these for outputs, and I wouldn't hesitate to use these. The pictures should give you a clear idea of what you'll receive.
