Hi dudes ( sorry for my bad english, i'm bulgarian after all ) !
A friend of mine gave me a few flybacks and so i decided to make a plasma globe and speaker :)
1. So i made this circuit for the speaker MEDIUM

, but it didn't work ;( I hooked up the 10 ohm to oscilloscope and both with and without signal it looked like this 1cfb955bf763b6d83f8c843f0f0156dd

( i drew it quickly so ... :) ) and what ever i tried, even changing the TL494 - it didn't change ;( So what's the problem ?
2. I almost forgot about the globe - what is the best circuit for it ?
