It is the most similar thing that I have listened to not having preamplifier.

My most respectful greeting to the gentleman that has designed it.

Hello Onvinyl.

Important the circuit that the one use of power suply. The same philosophy that of Walt Jung.

That circuit contributes to its sure sound.

Small modification.

I believe that you are right the only thing that there is changing is some transistor for an operational amplifier.

Uhm...

What kind of volume control are u using????

 

[Angel Puerto]

For the audio tests I have used DACT 10kOhms, that they have left me.

That of the image is an Alps.

Without a doubt I should buy myself this Stepped Audio Attenuator

Hello

The operational amplifier of the power suply is a NE5534AP.
Does a better alternative exist to this component LM... TL... AD...?
