New! WNA MKll Head-amp kit.

post #1 of 760
Thread Starter 
I had one of my rare (and to date least sensible) Head-Fi moments last night where I thought I'd delete all 4,674 of my posts (don't ask) starting with this thread I managed to wipe out my posts on page 14 and page 1 before retiring to bed for the night.

The posts are apparantly wiped from the server so I'll have to fill in the "dots" from memory... ah the silly things some people do when they're hot headed.... I'm just glad that I didn't wipe out everything.

EDIT: ****! appears I actually reached page 2 as well.

I look forward to your review of the finished item Mike. I suspect I'll be building one soon. I've justified it to myself that I can relegate my original WNA to my study/PC room for use with the SR-80s and I can build a new one for use in my main rig with my new HD650s. I must get my X-Can V2 on eBay!

Looks like the new PCB will still fit nicely into the Hammond with room for a crossfeed. Are you building a complete kit or are you doing your own thing with resistors, capacitors, case and all? If so, what are you using?

EDIT: Looks like the board is designed for Natai output capacitors? I suppose that you can use flying leads from those component locations if you want to use beefier (and physically larger) ALCAPs?

How can I purchase a kit or PCB from the US? I'm quite interested.

[edit=What case do the boards fit into?]

Also - are the original PCBs still available?

Very nice, with both the pot and jack on board some very neat amps are going to be built

Is there a parts list somewhere? (So I can work out the cost)

Looks very attractive.

If the cards were 100 mm wide they'd fit the slots in Hammond cases, like the N16 that the PPA uses nicely. What's the idea with 90 mm wide?

It looks like one could get 12 hours from a bank of 20 AA cells, would it be crazy to attempt this as a portable amp? I remember people lugging around Kaypro computers and called them portable...

Hi doobooloo contact Dr. White by clicking on the contact link at http://www.wnaudio.com/ You can purchase either the PCB1 or PCB2 or a full kit.... the full kit is £160 but I don't yet know if that includes PCB1 or PCB 2, full details to follow. All I know at the moment is the PCB1 is £30 and the PCB2 is £35 I'll get the full details asap.
Thanks for the details Mike! I'll keep tuned to this thread for more info.

Good point there. I wonder why it's not just a standard Eurocard size like the PPA, it would have been much easier that way for many DIY builders (Hammond, Lansing, etc.)...

A question: even with the design changes to the LM6171 standard for the WNA board, can it still function with the AD8610 opamps?
