Default Re: 807 tube amp, any ideas?

Joe mentioned the versatility of the 807.

The most surprising place I found them was one as each Y amplifier of the old Cossor 339 oscilloscope. Running very low power. There doesn't seem much the 807 cannot do though the heater power may make the efficiency daft in low power applications.

There's a lot of 807 still in the wild, but no-one's making any more. They are, however very long lived and very hard to kill. 5B/254 and 5B/255 are rarer, and also not being made.
