Manu is a serious contender to join the exclusive club of: Top OT thread starters His writing style is getting very close, he only needs to start a few threads

Nice layout steen.
I didn't know I had a writing style, Thx.

- I've made the test with no ( ) Output pot at output.
Good news for the masters : it works bestissimo.
I can now crank up the volume to very very (up to much too) loud level without any noticiable (hearable) distortions. Seems that there is (more than) enough gain.
Aleph 5 love to be driven by such a fine and powerfull bride.
The sound is pure magic, only.

As for further tests, obviously you prepare yourself to take over, I see. HeHe.

Waiting for your first impressions.

I am pretty excited about how this thing will sound connected to the F4, with or without bunnies Especially now when Manu talks about loads of gain. I will use two such batteries in series, with a BG or similar (smallish) cap for smoothing out the DC. Manu, you are not off the hook yet I am just foolin' around from the sideline Back to work

Steen

BTW did you notice the ugly blue boards on the pic??

Anyone compare this preamp to the original BOZ. I have been using the original for several years and have been quite happy with it. But if the JFET BOZ is a significant improvement, it could probably be implemented on the BOZ board with little effort.

Me again. The proto is up and running, and I beleive this is the ugliest proto I ever made Call me Lucky Luke if you wish, 3 hours (including visitors along the way , took at least an hour to get rid of ..... ) It sounds pretty good though! Actually I am quite surprised! No fine-tuning at all, I simply adjusted the input trimpots to half value and hoped for the best It really rocks the F4 to clipping....he-he I didnt count on that but nonetheless... The sound is better than expected. The supply is simply a 330uF Black Gate for feeding each channel. Since the original sch. doesnt have any decoup between the channels, I though it would be best to feed each channel from its own cap...pheeeew The batteries are working out extremely well indeed. With no signal and the volume at full throttle, I can hear no hum/noise whatsoever with the ear right next to the effecient Fostex 166's That was even less expected. Battery supply rules Pheeeew again I am off to some more listening (and finetuning along the way!!)
Have a look, ya slow bunch......
Steen

Edit BTW the album on the pic comes highly recommended from yours truly! Soft listening for the hard guy's! Even the girlies like it!!
