The Phono Stage

[toufu]

I would recommend this circuit: http://www.diyaudio.com/forums/audi...hip-amp-kits-dacs-chassis-78.html#post1123520 with shunt regulators as in MC phono project.

Thanks Peter, I will give it a try. Will the opamp fit on a regular project board that I can get from Radio Shack?

Yup, but also known as The Source now

Hey all.
Well, Peter, all I can say is that every time you put forth a design it is always well thought out and truly professional looking...Congrats on that!
I am considering building one of these to replace my ARC PH3SE, which, while a truly nice piece of gear, just doesn't really have enough gain for the LOMCs that I enjoy using.
I am wondering - has anyone done any subjective comparison between this and any other good phono stages? I have quite a bit of listening experience with the Pass Xono, Whest 2, Rossner und Sohn, but ultimately would like to build something...
Regards,
Byron

Wrong! They are known as "The Shack" now.

North of the 49th it was rebranded as "The Source" when Circuit City bought them...

Well, I know a guy who used to listen through ARC PH7 to his heavily modified Versa Dynamic with ZYX Universe. After he tried this phono stage, he "hates" going back to PH7

HI Peter


not sure from the thread but is the kit ready to be bought??or just the boards? if so how much?
Usual paypal address?? Amount with postage to UK?? etc etc.

 

[Peter Daniel]

The boards are $40/pc plus $6 shipping, usual paypal address.

I still didn't decide on a kit as a total cost is quite high, but for now, I can supply most of the parts including V-Caps. No BGs though, as sourcing them presently is practically impossible.

Hi Peter,
Is there a special reason for using such expencive Current regulator diode ?

 

[Peter Daniel]

J511 is not really expensive if you know where to find it. I've been also successfully using 1N5314 as an alternative. The board is designed in such a way that you can basically install anything there.

"K" is additional pad for axial components (also means Cathode).

 

[Jan Dupont]

Then I don't know where to find it
Either €10.00 or Obsolete/Discontinued.....

 

[Peter Daniel]

They used to be on ebay at $2.50/pc but I don't see them any longer. I got mine through a friend from a supplier in Poland.

You can also get them from me at $2.50/pc

 

[Jan Dupont]

I was just courious about the design, and no price listed in BOM

 

[Peter Daniel]

So no particular reason, if that answers your question

 

[Jan Dupont]

It does
The J511 isn't as expencive to you as it looked......
I was just wondering if there was any benefit from using a €10.00 component there, when you can get a similar for under €2.00

 

[Peter Daniel]

Still would be useful if you can suggest any similar, readily available substitutes.

I was able to get the J511 from HK, 4 for $10. Also, the 1N5314 really is easy to get. In fact the hardest part for me was remembering which IEC inlets would fit Peter's boards. Got some that were too thick, so if I were to make a recommendation on the BOM, it would be to put in the PN for the IEC inlets that fit.

 

[Peter Daniel]

But of course it says right on a board: Q218 (DK part#)

Peter, DK?
