Why does it take some time for the Etherwave to warm up?

I have read that one should let the Etherwave warm up for a while. I have an Etherwave Plus, and I've noticed that the pitch field will expand for a while until it's warmed up.

I'm curious, though, about why this happens on a solid state device? Very interested in the forces at play here.

as far as i know, all that analog oscillator related stuff needs time to warm up. may it be a synth or theremins. i don't know for sure how much the capacitors are involved, but i'm pretty sure it's because the transistors warm up. the coils and the hf-transformers are temperature sensitive, so they change whenever the room temperature changes. that's why you have a winter and a summer tuning. :lol:
i still think that "the art of electronics" by horowitz/hill gives a good (and sometimes funny) introduction into the subject. it's available as downloadable .pdf from the web.
