[heinz1]

JFETs just arrived in good shape. Many thanks, Mark.

Hello Patrick,
I received my boards in perfect shape.
Now, I've only one question before starting:
every Sen channel need an indipendent floating PSU or I can use only one psu for both the two channels?
Thanks
Ciao
Guglielmo

 

[qusp]

every sen needs one

 

[EUVL]

Every single ended channel needs one, so a balanced channel would need 2.
Stereo balanced (2 channels) would need 4, which is why I suggest batteries.

Patrick

 

[qusp]

yeah sorry i should have been clearer, by every sen i mean every convertor circuit, which can be a channel or a phase of a channel

 

[mravinsky]

Jfets received. Thank you very much, Mark

 

[MarkLai]

Have fun!
Mark

Exist an evaluation pack (pcb+heatsinks+fets) for SEN I/V with ES9018?

Cheers
Felipe

 

[EUVL]

Yes, what we called the Vref version, or Version 18 (for ES9018).
Please plough through the thread. It's all here.

I want to order one evaluation pack for Version 18, how much shipped to spain?

 

[EUVL]

Please kindly send a PM or email to MarkLai.
He will check stock for you and give you further instructions.


Thanks for your interest,
Patrick

 

[merlin el mago]

Thanks Patrick.

MarkLai you have pm.

Mark has been getting a few PMs enquiring about the XEN IV V18 Evaluation pack and corresponding set of 16 2SK369V JFETs.

To simplify things, I propose to start another interest list here.
It is easier for us to handle these as a GB.

We have checked that we have sufficient PCBs and heatsinks in stock (at least 12 sets).
We currently have one more set of JFETs in stock, but can source more given sufficient interest.

Price is (including Paypal fees and registered post worldwide, Free On Board) :

XEN IV V18 Evaluation kit ________ 63 Euros
Matched set of 4x4 2SK369Vs ____ 60 Euros

There are others offering 2SK369Vs here. You might wish to shop around a bit first.


Please state your interest here again please. For example :

kannan_s ______ 1x V18 Eva Pack, 1set 2SK369s, 123 Euros
merlin el mago __ 1x V18 Eva Pack, 63 Euros
ymwong _______ 1x V18 Eva Pack, 63 Euros


Thanks you for your renewed interest,
Patrick

[NicMac]

Would a "SEN-only" XEN V18 evaluation kit be possible?
I still have the CEN PCBs/sinks from my first evaluation kit so I don't really need more of these.
Cheers,
Nic

 

[EUVL]

Already going for the next 2 channels ?? 😱

As a special thank you to your work on the SEN V18, yes.
Contact me by email and I shall get Mark to contact you directly.


Patrick

 

[NicMac]

Certainly!

But the next 2 channels will be made with extreme care for layout detail and quality components to match the SEN so that you will not call it "quick and dirty" next time😀
