diy IF transformers: first attempt.

[pamphonica]

What a nice experiment, and clear results. I might use it at the radio club one day.
Just a thought, but would this method make the transformers a bit microphonic? Tapping on the case of the radio would vibrate them and that gain variation might feed through to the audio. Maybe they could be fixed to a thin fibreglass support with epoxy or nail varnish once the spacing is established. Any thoughts anyone?
