I Changed over one of my C12s to a 251.
For sale C12 P.S.B and Power Supply boards fully built with Chungers kit
and polys.
$130.00 shipped to CON U.S.A.
Just out of interest - how come you went with a new kit rather than converting the C12 circuit to a 251 circuit (I also have Chungers kit but want to do a 251)
I went with Poctops white 251 P.S.B.s. http://groupdiy.com/index.php?topic=55010.0
It has the true pattern switching with the 3 pattern select on the power supply and 3 relays on the mic board.
I think the P.S. is different to power the relays.
I just thought it was more like the original.
