I followed this post, and it's looking very promishing !!!.

Steenoe, i would be very pleased, if you could post your'e setup including the connection of the volume-regulation, and the size of that. ...

Well, it's not that i got the time right now (finishing up my pearl/dac/switch/psu enclosure's). But i allways have the problem, with 'a little too little gain' - So this could very well be my next project.


Jesper

Steen is the man! Is this the robust preamp Mr. Pass promised? R Cray is my man too! Battery ps is the way to go with a simple circuit like this. Parallel a couple more and it should last a lifetime

Steen: lucky luke is an slow motion artist compare to you. Guiness book of record candidate? May be?

OK, F4+JfET BOZ will be my next Niravana.

Don't forget : with this pre fine tuning is part of the game.

BTW : I confirm, proto is Uglyssimo.

I have no idea, but robust it is indeed! Man this little thing rocks the place to no end. Its even more powerfull then the NS10 Me surprised to no end!!!!
I might even consider to go dualmono, using 4 batteries I am blasted off my chair Build one and listen for yourself! There is not even the slightest noise at full throttle!! Takes an hour to solder this thing together
lykkedk, the pot is a 10k logpot at the input of the preamp! You are more than welcome to have a look (and listen) for yourself.
Ohh, the battery holder is there to keep them from bouncing around...........He-he

NICd or NiMh

whatever combination ;say one 12V/4Ah plus one 6V/4Ah in series ; or two twelves ; or yourfavenumber of single cells ;

charger - LM317 in CCS mode - Icharge set to 1/50 to 1/100 of declared current capacity , so there is no need for any schmanzy elektor like processor based clever circuit - you can leave it on for good,and switching it off only when you listen da muzak

I know that........... I've run Quad 33 for 3 yrs that way ,with one Yuasa 12V/7Ah

oh boy,how clever I am!!

...will the commercial version come with a roll of battery holder?

Steen, Would you say that this compares favorably with others - the X-Bosoz in particular. I know it is still early... but it took you long enuff to get one together

Steen, I had the same impression listening this afternoon to shostakovich cello concerto with Natalia Gutmann.
"I am blasted off my chair" Thats the point. Nothing to ad.
