Yes they alll right. In first attempt the oscillator circuit was 1n+1k pot+470+1n. But after I saw 18Khz then they replaced with 2.2n+150R+2.2.. But nothing changed.

I already changed it one time. However my 2092 stock level is only 2 pcs...
Anyway, I think I will go with IR2110 1200W project..
But thanks a lot for your close interest.
