Default Re: Modifying an inductor?

A successful bit of breadboarding confirms that the values now are near enough correct. Using the circuit below and a TTL-level square-wave input, I get a peak sine wave output a few cycles under 1MHz - I have ten 15ÁH chokes to try, so I'm sure one of them will be closer to my preferred frequency. I have a choice of poly 3n3 or ceramic 3n3 - both work, but will it matter which I use?
