Default LM3875/86 PCB

hi people long time no write.

in that long time have made pcbs that accept both LM3875 and LM3886,this is by connecting 2 smd contacts.
now after some time testing i would like to sell few boards that i have left lying around and am curious where i could do that, is there some subforum or something.

schematics is pretty much datasheet , but there is also second version(first picture) that uses smd components and have dc servo,there is third version on way but that is a bit of other story.

if this is wrong place to ask this i am sorry, admin please re/move.
if this is correct place then please ask for details if needed...

You may find you'll get more traction in the Swap Meet forum, and if you mention a price, including the cost of shipping.

Also note that the LM3875 has been discontinued by TI.
