 Tube_Equalizer_Schematics?
Has anyone schematics of tube-equalizers(especially parametric?)  
Thanks

I have one for a graphic eq, 6-band I think, but that can be expanded (also read RG's eq article). You'll need inductors for this type of eq, and hefty ones too, for the lower frequencies (1H?)  
If you want I can get it scanned, let me know.

If you look in the Groove Tube book at the Fender schematics, there was a seventies Fender amp that had a tube graphic EQ, I don't recall the name (maybe a Super Reverb or Quad Reverb?). It had six 6L6 output tubes and a dreadful OD section. The EQ used inductors and a probably hard to find center tapped 100K pot for the frequency controls. May be worth a look.
