Correct....Your DC protect board has the stock Zoebel network on it. Those 4 resistors are part of that. Joe's backplane board has the Zoebel network built in, therefore Ben's board is not populated with those components...

Yup, I read that on the earthlink site, another reason for buying the backplanes ;)
Actually I'd love to oreder them, but the custom fee is a huge pain in the ar**

Florian, if you install a set of backplanes, you need to dismount R1, R2, C8, C9.....on the DC protect...

The DC protect hasn't left yet so I will dismount those components...
Sorry for the uneeded work...
I'm planning the installation of the backplanes and I read that Joe advises to :
"The trick we use to bring the board up is to install only the pre-drivers in locations XQ11 and XQ12. This allows you to check out the basic offset and bias functions before installing all of the output devices. It is a good practice.
"
I couldn't find any up to date instruction for bias adjustment on revD driver board (and even then pictures are not accessible anymore) but I suppose that it is described in the assembly notes of the RevD driver board.
Are they available somewhere?
TY in advance,

Lucky you, it reminds me my birth place in southern France, close to the Pyrénnées Mountains at the border of Spain, not many people neither and a great place for fly fishing ... Can't wait to turn back home for good... :D

Ah ah ah, the only little things I know about Wyoming I learned them through A River Runs Through It, having seen your profile picture I knew you was into it : )

The big advantage in the Pyrénées is that it has a great variety of spots, mainly mountain streams we call "gave", the atlantic see being close enough, you can make some pretty salmons if you're handy enough. I used to fish with my father who teached me, but, man, these are maybe 15 years that I haven't been seriously fishing (aside of a couple of interesting fish parties in the Swiss Alps when I was living there)...

Ah, Florian, last year I actually got to spend 3- two week periods on my favorite stretch of the North Platte River called the Miracle Mile. Lots of Big Fish. 4,000 to 5,000 fish per mile, great tailwater fishery....

Got to love your life Lee, our rivers aren't of course that fishy, and fishing is highly restricted down 1km to the sea side during winter...
BUT hand fishing, that was my father's speciality is authorised :)
