DBC/ DBU made by the blitz?

[wibblywobbly]

They were made by Darkith, pretty much a garden shed operation, either as self assembly kits or pre-assembled.

They worked well, I had a few, but along came Clark and for little extra money there was an all singing all dancing board that fitted straight into any tank.

They are still available:
