i checked out that link and it appears one of those cases will cost around $70Canadian shipped...

heh...anyone selling bpa300 pcb's yet?

Has anyone figured out how to order the cases?? I think this has a lot of potential. Looks better than Hammond and way cheaper.

I'm down for 8 boards!

Very nice and clean construction, Alex... But try to think about different input amp - DRV 134 have little bit " synthetic " sound...

How about the SSM2142?

I'm sorry, but I have any experiences with this circuit...

Do you suggest taking the DRV134 circuit apart and using other opamps in place? The resistors would have to be 0.1% and may be difficult to match opamps, no?

Upupa Epops · 14th May 2007, 06:05 PM

I hope, that in Boston exist shop, where you can buy 0.1% ones...

alexcd · 14th May 2007, 06:08 PM

eh... the Internet is wonderful. I can sit on my rear in Boston and have them sent from Texas.

I am interested in 6~8 pcbs. Please pm/e-mail me when group buy is ready to go.

What are people's feelings on using a non-toroidal transformer? I have 4x600VA 25-0-25 E-I cores ready to go.
