How is the 6F8G a replacement for the 6DE7?
I understand that they are both dual triodes. after that nothing about them is similar. at all. Ooh, the heaters in both tubes work on 6.3v they have 2 similarities.
Behaviorally they're identical to the 6SN7 -- looking at the specs between a 6EW7 and a 6SN7 the only real differences (outside of the socket) were gain. IIRC the 6EW7/6DE7 have a Mu of around ~17.4 (someone correct my values if I'm wrong), whereas the 6SN7 has a Mu of 20. Since the 6F8G is much cheaper than the 6SN7, I went with having those adapters made. There's a lot of talk about this in the Woo Audio Owner Thread if you're interested.
