Tube Chorus?

[frankm]

My next project is exactly that, low voltage submini tube phaser attempt #101, based on this schematic that I recently came across.

Hi all, this is my first post here  .... I'm working on a tube phaser project too but mine is quite different... Anybody can tell me if the schematico posted above is correct? It's basically 4 all pass filters but my troubles are about last stage: it should be a two signals adder but is that configuration correct? Thank you everybody

Tube Chorus?

Buy a Leslie Speaker.

A model 147 is all tube and the swirl of the rotors will give you all the whoosh you need.

dont know if this has been mentioned

Actually, no. At best you'd have a tube based phaser. Magnatone did a tube based vibrato in some of its amps. I did a triode phaser about 10 years ago, using photocells like the reference. It works fine, as you'd expect, because a phaser needs an accumulated and variable phase delay...

no need for a variable delay (just "wiggle" between dry/wet...  )
(see: Hammond, White...)

and a mixer, and you can do that with JFETs, bipolars, opamps, tubes, and probably magnetic amplifiers. 

or mechanically,
(see: J.P. White...)

Anybody can answer me about schematic above?
