Group order of non-inverted LM3875 pc boards? Anyone interested?

[BrianGT]

I made this board for the gainclone this weekend, based on the components used in Peter Daniel's unit. It is in non-inverting configuration.

Any one interested in a group order of non-inverted LM3875 pc boards?

For resistors, Caddock MK132V resistors were used for the input, shunt and feedback resistors. A Riken 680 ohm resistor was used for the resistor setting the gain with the NFB resistor. The board is designed with these components in mind, so the group order could also include these components.

As far as power supply capacitors, the board has room and component pads for using the BlackGate 1000uF 50v caps, Panasonic FC 50v 1000uF caps and Panasonic FK SMD 1000uF capacitors (new product).

I am also looking at making a power supply board to go with this.

Is anyone interested in a group order of these boards, and possibly also interested in a group order of the components used on the boards if we can get a substantial discount over single unit quantities?

Schematic used for layout:

(NFB resistor is to be soldered directly to the LM3875 pins.)

I am in on the boards and the other components as well. The PS board too if you design it. I guess that we can source our own caps as I am sure everyone will not want the same ones. I will probably be in for 20 or so channels worth. It looks like that would be 5 boards.

Thanks for taking the initiative. If you need any assistance along the way, let me know.

Hello,

I would be in for a couple boards.

Count me in for a board or two. Quite possibly for the resistor pack too if its available.

ill take a couple of boards and resistor kits

Hi Brian,

You know me, if there are boards for sale, I'm in. I guess I would be interested in a couple.

BTW, to those thinking about getting boards, if you need parts, read on.

If you're a Cardas fan, the 2nd annual Cardas bulk purchase is well under way. If you're interested see this thread in the trading Post Forum and the WIKI Page for details.

I have already started to send order confirmation emails to those that already placed their orders.

I will be accepting requests for the price list up until Wednesday, the 25th at 12 midnight EST.

PS: I will delete this post after Wednesday.

I prefer Peer peer connection and have made quite a few gc sets I would be interested in 2 boards provided all the right components can come with it.

Power supply pcb is not really essentials but, again, if they can come with the good stuff components, write me down for 4 of them !

Count me in for a couple of boards. Also possibly interested in component kits depending on what those look like finally.

I'm in for a couple (8 amps); more if the price happens to go down as people pile in.

I think it is great to stock up as these make great little surround or multi-amp setups, and they are much faster than doing P2Ps. Instant amps when you want to try out a new project.
