Default Bruno Putzeys Balanced Preamp - Group Buy

Dear all,

as discussed in this thread, I'm organising a Group Buy for

- 'blank' PCBs, and
- fully built modules

of Bruno Putzeys' Balanced Preamp / volume controller unit.

Here is the background and description of design and concept: http://www.hypex.nl/component/weblin...ask=weblink.go

PCBs as well as fully built modules will be professionally produced at Bruns Elektronik here in Germany.

Group Buy will start as soon as we have reached the following quantities:

PCBs: 30 units.
The price per PCB (stereo unit, 'blank, without parts) will be 23.30€ + shipping. If we manage to get to 50 PCBs, the price will go down to 17.25€.
PCBs are FR4 material, 1.5mm, double sided with solder resist, mounting print one sided, nickel/gold min. 0,05μ Au to IPC Class 2, visual and electric testing.

Fully built module: 20 units.
The price per fully built unit (stereo unit, professional series production, incl. parts) will be 334€ + shipping.
The BoM for the parts used (including ELNA capacitors, 1% Vishay caps, Neutrik connectors, Hypex HxR12 regulators etc.) can be found here: http://1drv.ms/1W0T7dR

I have set up an Excel Online spreadsheet for your participation here:
Please enter your user name and the amount of 'blank' PCBs and/or fully built modules you wish to order. As soon as we have reached the threshold of 30 units for the PCBs and/or 20 fully built units, I'll go ahead and place the order to start production.

For any further information or details, please contact me per PM any time.

Thank you,

As Jacco has pointed out rightly here, I should have mentioned in the first place that I have asked and received permission and approval from Bruno Putzeys to do this.
