[sdiy] passive ring modulator transformers

[alfred.pear at gmail.com]

Hi Again -

Neil, the LT44s are spec'd for 300hz to 3.4khz, which makes them pretty
similar to a lot of the audio transformers I've been looking at. Is your
general experience that they are fairly accommodating in the lower range?

Has anyone experimented with the higher-end transformers spec'd for 20hz to
20khz in this design?

It seems like most things will "float" here - I was just curious if anyone
knew about a particular (somehow affordable) transformer that perfectly
straddled the "real" and the 'ideal."  Should know better by now!
