Quite so, it took circa 5 hours.

Yes, they look good but I miss the gorgeous blue of beta boards...

First packets should ship this saturday.

Dario, What are those posts on C13? I can see using them on many other boards. Also, It appears you installed sockets at C9 only. Is that correct?

You must have been very pumped to build at that speed. I'm impressed.

It's my usual time for populating a couple of them, also for beta boards I needed circa same time.

Having had good experience with non-polar caps replacing the normal electrolytics in audio circuits, I will be ordering a batch of 220uf 6.3V CapXon NP capacitors soon. I am willing to provide a pair of these to each person that participated in the beta built and group buy for free. Please PM me if you have participated in either of these and would like a pair. Would also like to hear your impression with these whether good or bad. Personally I would recommend still using a 0.01uF FKS in parallel because this is not there audio grade cap (out of production).

Since this lot is pretty big, if anyone want's some in small quantities, I will probably be able to provide them at very good price. I will most likely be able to meet or beat the usual suppliers on the net. Please PM me if you need some as well. The only thing is that I get them about 8 weeks after I place the order. So please do not expect to get them in a hurry.

Question CapXon

Soonsc,

I am always curious about alternative approaches, especially alternatives to electrolytics. Can you point me to more information about the CapXon NP capcitors? I would like to learn more before moving forward.

Thanks

Jac

Just read through this PDF.

Dario, Are those small fastons gold plated and is there a matching female part? What is your source for those?

This is the data sheet I can find. I asked for the engineering bulletin, but it was not for open release.

I just tried a 330uF of higher voltage I had on hand in the MyRef C after swapping the position with the resistor and still using a bypass. Not earth shaking, but improvement is positively audible. Since it is hard for me just to get small non polar or bipolars around here, I just thought I'd order a batch which is also used in many places like generic chip amps.

Default Boards update

I've just talked to the manifacturer and they'll remake all boards in blue according the order.

They will be ready by July, the 11th and in my hands a couple of days after.

For those that may like green boards or simply can't wait I can ship green ones.

Please let me know what you prefer.

I'll wait for blue. Are you going to be able to keep the green boards as extras? If so I will buy two of them.
