Will be back - but I have sound Made it with a lightspeed attenuator. Everything is splendid..
I almost gave up on the lightspeeds some time ago..
Cheers
Thats it
Is it possible to use a double lightspeed in this circuit ? http://www.twistedpearaudio.com/docs/linestages/legato_3.1_schematic.pdf
I do not use that F...... buffer LME 49600 !

If used without bypass how good Is quality related to mundorf silver oil and obbligato premium gold
Fuller but a bit opaque.
Well done guys, enjoy. Pinnocchio, impressive build.
Thanks!
What is the input impedance of the DCB1?
I am planning on using the o2 relay based att from amb.org and need the input impedance of the next stage for resistor calculation.
Also is 25k a good value for the attenuator impedance? I've read that 20k is the best option but would 25k reduce the overall performance of the dcb1?

Don't know the output impedance of Apple gadgets. Find the one source's Zo value to be used that has the highest output impedance and use 10x pot that. If that means more than 25K, avoid that source. SNJFET RIAA is OK with 10K. You will have to augment its output coupling cap accordingly though.
Hi in our Hificlub we will use the buffer only for high impedanse sources. One member have a Audionote dac with 0,47 uf. as coupling caps. That is far to small for ordinary sources. Is it ok with the 220 kohm only and no pot ?
Yes.
Guys I cannot hear the relay click (12v relay note is jumpered)
Vout is +-9.3v
V across 10R resistors is 1.3V
All led glowing
Vgs of all mosfets 3.9V (+-30mV)
Input output not connected
No DC offset no voltage across relay diode.
What do I look at?
Thanks in advance
