Does anyone have a schematic for a single ended 2c26 or 2c26a amp? Otherwise, any thoughts about the best topology to use them in? Many thanks.

I have a few of these and should really put in some listening as I have an amp that uses 7193 so should be able to take a 2C26 . Initial testing on the AVO is that this device is similar to 7193 . I seem to remember gm was in the region of 2.5mA/V on the tester so probably more useful as a driver than an output stage . There are no published curves , just look for the CV1759 datasheet on Frank's site to get an idea of the specs
