B1 buffer

Hi all, thought I should post a pic. Thanks to Vince in the US this mostly finished B1 board turned up at Christmas. All I needed to do was drop in the Fets and hook up power. No case yet but Wow. I no this is a old project and Salas and co changed things up with the mezmerize but still this B1 rocks. Until now I don't think I have ever heard such clarity if that's the right word. I love it! Love it😀

Thanks Mr Pass and Vince

yes very nice.
At voices a little bit behind my aleph p, at rock metal and techno a very little bit better than aleph p.
I was very pleasant with the sound.

But have tried it with a little bigger PSU😀 (ca. 30000µF)
PSU was made of spare parts it is sold because it was really to big 🙄

I always think about to try it with a capacitance multiplier and later get this thing into a case.
but i dont know how to scale up a cap multiplier for more Voltage the most i saw runs at +/-30V

stijn001,

You sure you want to use power line filters on this amp?
Looks like you are using a CRC power supply reservoir. That should be enough.

Do you have a power/noise problem that requires them? They could choke off dynamics.

Nice looking amp just the same. 🙂
