[sdiy] Passive Ring Modulator/Transformer Question

[Joel Kirchartz]

I'm sure everybody here already knows about the passive ring modulator that 
is 2 transformers, and 4 diodes .... But I'm looking for a resource for the 
transformers .... they're 1:1 ratio impedance transformers that are 
center-tapped ...

I havn't had much luck finding them, and was wondering if I could use two 
audio isolation transformers wired in parallel instead.... I'll give ya an 
ascii diagram to give you a hint

Normal Transformer:
---)(---
   )(
---)(---
   )(
---)(---

Two Audio Isolation Transformers: (+ sign indicates the connection)
----)(---
    )(---
|---)(---|
+        +
|---)(---|
    )(
----)(---


Any Input would be Greatly Appreciated
