Ok here' s a quick-and-dirty page to show your interest in a possible group buy for these PCBs. As soon as I will receive the permission from Mr. Pass to organise the group buy, I will change this page into an official groupbuy one. The thread describing the PCB:
[Aleph-X compact PCB]

Please write down your UserID?, your location and the qty. of each part you are interested in.

Thanks a lot

Edit December 8th, 2005:
I received the no-objection from Mr. Pass, so I will bring this group buy further.
As for the prices, the situation looks as follows: with the quantities stated so far in this page, the prices would be quite high. To keep them down, I have the following proposal: I will order upfront a bigger amount of boards (at least 100 Mainboards, 400 Driver boards and 100 rectifier boars). This way, I will be able to keep the prices as follows:
EUR 8.00 for the mainboard
EUR 3.30 for the driver board
EUR 6.50 for the rectifier board

The board will be manufactured as follows:
2 oz. copper
Blue solder mask
White silkscreen

A complete stereo set (2 main boards, 8 driver boards and 2 retifier boards) will then cost 55.40 EUR + Shipment.

I am also organising parts for the rectifier boards. Ordering at least 100 part kits, I will be able to keep the price for the COMPLETE kit at 13 EUR. If you' re interested, please sign up (I have replaced the column for the MOSFETS with one for the rectifier kit).
The rectifier kit will include:
- 4 Heatsinks
- 4 rectifiers FEP30DP from General Semi (equivalent to MUR3020, with lower junction capacitance)
- 1 Weidmuller screw connector
- 4 Film capacitors and 4 metal film resistors

I've added a column for the IRFP240 groupbuy organised by Tarasque, just to keep related things together. Please note that all matters related to the IRFP240s will be managed by Tarasque.

UPDATE December 10th, 2005:
Prices for the PCBs are reduced as follows:
EUR 6.70 for the mainboard
EUR 2.40 for the driver board
EUR 5.60 for the rectifier board

It means, a complete stereo set (2 main boards, 8 driver boards and 2 retifier boards) will then cost 43.80 EUR + Shipment (instead of 55.40 + Shipment).

The board will be manufactured as follows:
2 oz. copper
Blue solder mask
White silkscreen
Gold plated pads
