Anybody using the new ESS Vout DAC (ES9022)? - Page 47

EUVL · 03:51 AM

We also have for internal use an adaptor PCB which converts either a single BF862 (SOT23) to TO92, or even a J111 cascoded BF862 into TO92.
If there is sufficient interest, we cam make those available pretty soon.

As agreed with Joachim Gerhard, who kindly offered the filter buffer circuit to all DIYers, here is the arrangement.

We shall offer, in a Group Buy with minimum 25 PCBs, the PCB for the JG Filter Buffer as posted in here :

Anybody using the new ESS Vout DAC (ES9022)?

On the PCB will be soldered a total of 8 Idss matched JFETs (4x BF862, 4x MMBFJ310).
We still need to calculate labour cost for matching and soldering.
But the entire package is likely to be around HK$350 (~44USD) including Paypal fees and registered air mail worldwide.

You will get a Bill of Material so that you can order and solder the remaining components.

This is a one time offer.
After the GB, the board is still available on request, but our normal conditions will apply.
i.e. orders under HK$500 will be subjected to a service charge.

We'll conform exact price in a few days.

You are real quick.

Would you be kind enough to start a GB thread for me (and you) ?

Thanks,
Patrick
