a new Bosoz made in France

Phill · 13th January 2005, 07:23 PM

hello

excuse my English!
I have much admiration for the work of Mr. Pass
and I make a point of thanking it for his generosity

I present a BOSOZ made in France
it is not finished
I put myself question for the mass ( ground ?)
is what that is appropriate ?

Great work

very nice

After finish, tell us how it sounds

Hello, I see you are using gears on your volume knob. do they disengage, like my BOSOZ?

Either way, nice work so far. Can't wait to see how it comes out.

Phill · 20th January 2005, 09:23 PM

thanks

the gears are fixed => no balance

I have a small problem on a channel : the report is for later...

hello

I finished the assembly
I have two problems

with certain discs, the sound saturates, not with all,some is volume .
it is similar with the other sources K7,tuner...
R3-4 is replaced by a resistance 1.5 k/2w...?
R18-19 : too weak valeure ?

I use an attenuator with 24 positions, 10K.(P3-4).
in position 20, volume is not very high
I don't benefit from the power of the amplifier (QUAD 405/2)
(R15=430 ohm !)

if not the sound is very good. my system is better
I am with the listening of all proposals

peut etre que PierreG pourrait m'aider pour la traduction?

Nice work.

All grounds from each inputs, each outputs and gain stage should meet at one point. This is termed "Star" ground, a short length of wire from the power supply regulator ground with all grounds meeting this point is best.

now, the masses are good.
there remains the problem of saturation.
it east can be possible to decrease the level of entry?
to see the preceding message

thank you with all

R18/19 should be 220R.

Do you use P1/P2?, Important to have input attenuator.

P3/P4 should be 5 K, 1.5 is a little and and will reduce output. See excellent article by Nelson Pass.
