B1 Buffer Preamp

supernet · 15th June 2008, 10:14 PM

I was looking around for quite some time trying to find a simple buffer to drive my high gain power amplifier and now I am really interested about this B1 project, so Mr. Pass are there any news about it?

Will it contain also volume control and selector as complete preamp unit?

There is a full DIY article scheduled to appear on EnjoytheMusic.com
at the beginning of July.

Also, you will shortly be able to buy one.

It looks like this from the outside:

I didn't see a source selector knob at the front panel.
Am I missing something ?

It looks having two inputs:

(1) Passive pre with no buffer
(2) Passive pre with the buffer

and one output to the power...

To me it looks like there 's no input cap, just an output one. Those small blue square things look like local decoupling PSU caps?

Maybe my eyes are deceiving me...
