No worries, I do it all the time. It will either do something better or it will wimp out on the lower impedance and sound like a tacky plastic vuvuzela.

Funny that today I heard the word vuvuzela for the first time and now you are writing it down.

I have seen some in the supermarket and wondered what could it do in front of my tweeters

I see you are using trimmers in the output....

Necessarily so. Its experimental and I don't know its best bias, since it will affect the buffer too. I have trimmers for the first stage in the back pocket also, if it will pull differently enough between channels. As for vuvuzela.... Mount a couple to waveguide your tweeters If you want your HF to give you err.. a buzz that is.

Spooky

I guess there might be someone that can pull real tunes out of the thing.

I used to see those on top of the big trucks (metal crome ones).

PS: I am not really into football so sometimes I do not grasp the funny parts imediately.

I am looking forward to read your comments about those ceramic caps.

As for the teflon bypasses, what are the values ?

There is always hope, well it takes some practice from the guy to the left to reach the guy to the right, but loving it is all it takes.

No hope, needs more than some practice to play like the master Miles Davis
