Wushuliu, thanks. Appreciate it. I'll take your word for building it and order the parts. I didn't realize the board contained part values. Now, we'll see if I can read the board. Here goes....

This should make a great partner for the dBop.

Be sure to add a couple extra resistors to each order just in case I missed one! (and it's always good to have spares anyway).

Ok, I have got the amp wired up. Would like another pair or more eyes to look over the connections to make sure that I have not wired it wrong before I plug it in.

I also screwed up and put the IEC connection on the wrong side, hopefully that does not impact the sound. If it does I will have to get the new back plate.

Sorry for loading so many pictures.

As far as I can tell from the photos, it looks right to me. The power supply and speaker connections look good. I can't really tell with the RCA conncections. It looks good!!

Thanks Steve. The rca connections has the positive going to the center post and the negative going to the ring. Hopefully, that is correct.

Well, I took my first steps towards a complete amp. I ordered the wiring!

If you guys are considering building the Pass B1, this kit is probably the cheapest way to do so. I have no personal experience with the kit, but some people on diyaudio have had success with it.

Well, I would have also ordered the RCAs, binding posts and IEC, but I'm waiting for jtwrace's prototype for all the specs. As a result, figured it would be no harm to put off buying the amp kit also, as I can buy some more music equipment now, instead.

I'm guessing it would be at least a month before the case is ready to go, ordered and shipped to me.

Except the seller has a serious typo. The kit only requires 18V @ 20mA not 18V @ 200 mA. And...(I could be wrong and this happens to Nelson routinely), I doubt Nelson is authorizing this sale, so he gets no profit from it, however small it is

. Go here, buy the kit and purchase the parts from Digikey, etc... of which there are so few. If sold out, then there are always fellas at diyaudio who fabricate their own boards with permission from Nelson. Get your elbows greased and DIY! It's part of the fun!

I also doubt the kits are authorized, but I did say cheapest, not necessarily the most ethically sound way to build the B1.

After removing the back panel off the NAD tuner and sanding off all the writing I decided
to go another route, went to my local fabricator. He bent up a new back plate out of aluminum
which will be much easier to work being a softer material and I don't have to paint it. That will
be a time saver. For those interested the cost was $3.00. A can of spray paint
must cost that much.................Bill

I think it looks great! You can get some orange varnish stain there too.

It looks a lot like my Hafler DH-500 but I like the wood better.

Classic stuff!
