I would be interesting to have someone building step by step with pictures involved, how difficult or time consuming would it be?

I'm just wondering, does it take a very high quality volume dial to make this sound good? As I know, the volume dial can vary significantly in price...Also, anyone has tried a nelson pass b1 buffer with a LDR attenuator?
Thanks for the photo, the diyaudio link, and the reassurance about building the buffer. I've looked for 25K Alps pots, and haven't been able to find one. Is it okay to use a higher or lower value? Also, any recommendation for the toggle switch to flip between one input and the other? Seems like it should be nothing special (Rat Shack okay?), but would love to hear from someone with experience.And I agree that it would be great to have a step by step build description, and some close up shots of the board as it is getting stuffed. I assembled a Daniels DAC kit once based purely on how the board was labeled for the parts, and didn't realize that I'd inserted the power supply caps backwards until I powered it up and they got REALLY hot really fast. Oops! So reading a schematic or a board isn't second nature for me yet.Thanks for all the help and support!Neil
You can go as high as 100k I believe for the volume pot. You can also use 20k. I'll add some links in the BOM, including switch.Hm. Maybe I'll order a pcb and do a step by step w/ pics and then sell the completed build at cost...
I will add a bottle of Scotch if you do.Mariusz
Do you have part list for the toroid transformer and where to buy. Thanks
As to the pot I did not use one, instead I grafted a Lightspeed Attentuator (early kit version) - for more details of this go to DIY Audio.If anyone wants to know how I modified the B1 to fit the LSA please say so and I will post in this thread if that is OK with everyone.
