Those Sanyo dynamo are cool. I have one i've had since 1982 and I loved it until it... failed. Bearings started screaming bloody murder and not generating any power. I got a NOS replacement, and it... failed. Same way. I got... eh. Long story short, I now have four or five of them, and they are all inoperable. I won't be trying again. Anyone want one? Make me an offer.
I have a couple Soubitez ones that are less elegant but seem better lubricated. I've used one for a year or two with no problems...
In principle I think these are a good idea, but the Sanyo ones did not work out.
Thanks for this info as well. Hmmm . . . by the sounds of it, the Sanyo dynamo would not have worked out well, anyway.
Soubitez? Are they obtainable? What are my options? Thanks!
