Hi,
if you already have the speakers and the amp then adding a B1 is cheap. You can breadboard it as an experiment.

To check gain, just use a passive pot, it will have the same maximum volume as a pot + B1

Me and Les wants to impart a Zen spirit to this pre-amp. I bought a rubber wood the other day, painted it with maple varnish and burned some portions to achieve a "bird's eye" maple effect.Then I attached it to the sides of the B1.

Borrow a 25W to 30W amplifier and listen to your speakers at home at the levels you like.

endrik35 -- Your build is beautiful! Very well done!

May we see some photos of the inside?

Question - what did you do to make the "Pass" logo on the front? It looks nice.

Re: Pass logo, there's a sticker shop here in the Philippines which uses laser to cut acrylic plates.

Finally my turn to post pictures of my complete B-1. It is a balanced version (or RCA) and it uses 2 DRV-134 (Per Anders PCB) to convert the RCA signal to XLR. A word of caution: I had to use 2 separate transformers to get the DRV-134 to work with the B1.
Cheers to all,
Eric

6L6,

I apologize if I missed in this thread or your build thread but where did you get that chassis from for your B1? Thanks.

James

I got it from a friend, who in turn bought it from a now-defunct supplier called (I think...) DIY hifi enclosures.

Look to Par-Metal or Modushop for nice enclosures.
