Title: Is it Possible...
Post by: petemoore on September 16, 2003, 11:55:50 PM
To use a transformer and diodes like for the Tychobrahe Octavia, but using an opamp for the gain?
 Has anyone tried tying the last stage [transformer and diodes..vol] of the T.Octavia using another type of fuzz ckt?
  what specail properties of the rest of the T.O. ckt are needed to use the output transformer and diodes?
  I have a bunch of transformers for the T.O and might like to build something different...Also ... any Ides here?

I'm going to mess around with this I think.
 The Tyco Transformer is 3-4 to 1, Scott's Octave Screamer's Iron is a 10 to 1 ratio...I don't know [exactly/remotely] what difference this makes...what is required to 'drive '?' it & the diodes...

The Brassmaster is another circuit that uses the diode/transformer clipping scheme.  It's designed for bass, and the fuzz seems a little more tame than the Octavia- I guess a little more just straight octave, and less ring-modulatory sounding stuff..
