Interest for Final GB for F5X Power Amp

EUVL said:
The 20 heatsink extrusions have finally, after almost 6 months, arrived safely in the EU.
We are therefore ready to proceed with the GB.

We shall update you with regard to the PCBs and the matched devices within the next week.
The aim is to ship those beginning of December.
So likely to call for payment before last week of November.

A separate GB thread will be created for the case GB.
This will require a pre-payment before the workshop can start machining.
It will not be run by the XEN team, but my our dear friend CeeVee.
He is most certainly doing this for the love of DIY, if you know how much trouble it is.
And his gorgious work you can see here (this one his own design) :

Please keep an eye for the next days.
If you are no longer interested, please let us know so that we can give the chance to someone else.


Many thanks for your patience,
Patrick

A further update :

We placed order for 10 sets of F5X Power Amp PCBs today.
Each set consists of 19 pieces of PCBs of various sizes, 60 of which 70µm (double the price of 35 µm).
We need to charge 1350 HKD including Paypal fees and registered air mail.

In parallel, we offer (optionally) a set of matched devices.
These are curve-tracer matched ( for both Vgs / Idss and Yfs ) from a pool of over 1000 devices with our own matching tools.
The latter is proven to be < 0.3% long term accurate.

A set include :
1 set NNNNPPPP Toshiba 2SK170BL/2SJ74BL (PJFET degenerated to match Yfs of NJFET)
1 set NNNNPPPP Toshiba 2SK1530/2SJ201
1 set NNPP 2SK3497/2SK618 for regulators
4 XEN Audio Type 0 JFET heatsinks

Price of PCB and FETs together is 6500 HKD including Paypal fees and registered air mail.

We ship FOB (ex-work), and are not responsible for losses.
If you wish to ship by Courier door to door, you pay for those extra.

We shall ask for Payment around 20 November and ship by early December.
Please indicate whether PCBs only, or with FETs.

CeeVee will start the case GB in the following weeks.


Many thanks for your patience and interest,
Patrick
