FS: DC protect using SSR

I have a couple of new mono speaker DC protect pcb's.
These have dc protect and power up/down detect.
About 350WRMS into 4 ohms or 700WRMS into 8 ohms.
No transformer on board so you can choose your own to suit your local mains.
0-9 0-9VAC 5va separate transformer per pcb.
£12-99 each plus p+p.
p+p is £3-99 to uk and £10-99 rest of world.
