I've received the boards and have some photos of one that's mostly completed.

Here's pricing...

$12 for just the PCB, or $25 for the kit.


"Kit" means all the parts EXCEPT:

Transformer
Opamps
Resistors/Caps for LT and subsonic filter

I won't include these R's and C's because they will be different for every application. It's 8 resistors and 6 caps.

$5 shipping (US only)

Add $1.17 for Paypal fees (2.9% + 0.30).

So one kit will be $25 + $5 + $1.17 = $31.17. Just the PCB would be $12 + 5 + .79 = $17.79.

Getting parts from me saves you $5.

I currently have a limited supply of extra boards. If it turns out there is a lot of interest, I can order more boards.

Please email me directly if interested.

-Rob

It's listed in the BOM on my page, but I'll repeat it here to save people the trouble:

Transformer: Amveco TE70012, Digikey P/N TE70012-ND $10.76

Opamps: Burr-Bron OPA2134PA, Digikey P/N OPA2134PA-ND $2.63

You can use just about any dual opamp. The OPA2604 would work fine, TL072, and there are a bunch of National and Analog Devices parts that will work too.

Hi Maxhawk,

I'm running stereo subs. Do I need to install the power supply on both boards? (I need one for each channel)
Also, what is the "rated" output of the power supply? I may want to run my electronic x-overs from this power supply so I can have it all in one box.
Thanks,

Ed
