I just placed my cinemag order with the group buy... ordered the PCB version in hopes the Jack would graciously allow me to purchase a PCB... so i am anxious as well ...

Thanks for the update.

Default Need for help

Hello everybody,

unfortunately I did not manage to find a copy of the article up to know. There seems to be not reasonable possibility to get a AX subscription here in europe. Could someone help me with an unofficial copy of the ImPasse article.

Thaks

You can order a single copy of the article (Feb, 2009) directly from AudioXpress

Try e-mailing custserv AT audioXpress.com (fix e-mail addy appropriately) or Sharon LeClair

sharon AT audioXpress.com

I ordered a single copy for $7 (including shipping in the U.S.)

Solder fillet looks a little light on Pin 9 of the 9 Pin socket.

R25 looks a little bent too!

When did you say the GB was?

Including shipping to the US, they cost me $7.08 each -- that takes into account a free board for SY. I do have to recapture the PayPal fees and shipping (Priority), so I figure $12.55. Outside the US there's a fee on FX and priority Mail is $12.30.

I used the wrong pinout for the DN2540N5 -- so the device has to be flipped and manipulated a bit. Looks like a pair of Irish step-dancers:

If anyone wants, I will include 4 devices soldered in correctly, with heat shrink AND the correct R5 for 8mA. It only takes a minute or two to get it right -- I have used 2k2 in parallel with 300R (=264R) and one channel is 7.98 mA, the other 7.96mA. PM me if this is what you want.

The octal tube socket fits fine but some octals may need to have their pins bent a bit to fit.

I have yet to test the critter -- I just got done soldering them up.

The Sowter transformers fit just fine. I figured the spacing from their engineering drawing. I would expect the Cinemag's to work the same.
