Re-tapping a DRRI for 240v

noisepolluter

Anyone got any instructions? I’m guessing (hoping) it’s a connector swap as with the blues junior, but slightly more faffaliscious as the chassis has to come out?

It’s basically the same - swap the white/black (230V) and black (240V) wires, which should be on P2 and P8.

Hmm.. doesn’t look like I can swap them after all... P2 and P8 are soldered directly to the board rather than connectors. There are board connectors labelled CP2 (white with black stripe) and CP8 (black) for leads coming off the transformer though?

It's CP2 and CP8. Some models seem to have the C printed, some don't.

Brilliant, ta. Have swapped them over.

It works! Runs cooler and slightly quieter. Ta.
