SangeanADP-PRD18 Switching Power AC Adapter for models PR-D18, PR-D4W and CL-100 (Black)

How long is this adapter?

Does this work for the wfr-28 radio? looks exactly like mine that broke

Does this come in white? Sounds like some people wanted black and got white. Can you specify?

Will this adapter work on my PR-D6 ?
