Hello!
I decided to use a 6cg7 for a Schmidt Phase Splitter. I am still undecided on the choice of the quiescent point. What is the best? Please, help me!
Alessandro.

Hi Allessandro,
6CG7 is a 6SN7 in a noval envelope (slightly derated plate Pd, but this doesn´t matter for your app).
Thus, any Schmitt splitter designed for 6SN7 should give suitable operation point suggestions.
For an example, see p670 of RDH4 (ECC32 = 6SN7).

Really?
I heard this many times but specs in the datasheet look very different. In fact, recently I designed a schematic for an ECC32 + #50 amp and the builder tried to put 6SN7 in it, and it didn't work, voltages were all wrong.
Hi Giaime,
regarding ECC32 = 6SN7,
at least the german "Röhrentaschentabelle" says so.
But you are right: Glancing over the specs sheets, data is not identical, I agree. But not very much off either.
For the Schmitt splitter app under discussion, the mentioned RDH4 example still should give a good starting point for 6CG7/6FQ7 or 6SN7 usage.
