Hi, Has anyone used a GU50 in a SE U/L amp? I'm thinking of doing that. About 400B+ with around 75 ma cathode current. Load likely in the 3-4K range. It looks like it should behave about like a KT88....

Good listening
Bruce

I did once build one.Of some reason it was scrapped, maybe because I wanted the components to build a 50CA10 SE-amp.
Let's see what I can come up with ...

Yepp, here it is: http://www.pastisch.se/tubes/gu50.htm

I used the top schematic with EC52 driver.
