OK Guys, thanks. I'll try 9140 in for Q6 and 9240 for Q3, and put the Fairchild parts in if/when I can get them.

Cheers

Nigel

do not mix them ;

use same parts - if you can - in both halves

they are cheap enough anyway ...

regarding Fairchild parts - I'm not loosing my sleep about that issue

Harris parts are long gone, it seems.

Try Toshiba - 2Sj200 and 2SK1530.

Slightly lower Crss and Coss, but as Zen Mod wrote - it's negligible, don't fret about it. I can only agree with him that even IRF9540/IRF9640 will do fine here

Can I have a vine this time instead of beer (unless it's Pražský Staropramen or at least Velkopopovický Kozel)

Thanks for all the help. I just pulled the trigger on a purchase through Farnell-Newark in SP. No Toshibas or 9240s, but the others were there with IRFP9140 at the best price, so that's what it will be!

Cheers

I have no idea what that means, but if either of you find yourselves in Brasilia then the are on me!! Down here more likely to be beer or cachaca, although you can certainly have vine-products if that is your preference

Um abraco (as they say down here...)

Juma and me - we are teasing one another ;

it's related to usual punishment on our local ( Serbian Diyaudio) forum, where most used penalty is "Marš na pivo!!" , meaning (probably impossible to translate ) "*uc* off & have a beer!!"
