Item details

You know you pour over tube manuals every chance you get and visit DIY audio forums online and don't tell anyone. But you might have missed this one; Tung Sol's 7719. Take it from me, it's a sleeper.

I don't even know of one commercial piece of gear that uses it, but I fooled around with it and it's meaty and when allowed to draw a healthy plate current, very linear.

It's a triode with 6 watt max plate dissipation so you could use it as an output tube in a horn-loaded system or headphone amp.

12.6 or 6.3 volt filament operation so you can use it transformer loaded to driver for output tubes with 6.3 volt filament (6L6, 807, 5933, etc.) or output tubes with 12.6 volt filaments (12V6GT, 1625, 6883, etc.) without separate filament transformer.

Now take a look at the curves around Eb=-3 and Ib 30 ma - they are quite linear.

Wanna know what's preventing this from being the bomb? It isn't used (yet) in Japan. Sorry folks, like it or not, the rest of the DIY audio world copies Japan. If you think the SET revival and craze started in the US, learn some history and while your at it make some history by trying something new.

used, very clean, branding worn. Tested
Come and get them.
