Hi,
I'm clearing out my loft and have a Fluke 3330B that was one of the first things I bought to try and repair, however it's missing a board which at the time (many years ago) I seemed to think was the pre-regulator board? It's also missing the top cover. Everything else appears to be complete ... although look at the photos.
I always had a plan to either find a spare, or even make my own version of the board, but I ended up with a selection of Datron calibrators and never went back to it.
Even if not intending to repair there's a whole lot of useful spares in there!
So any interest? Make me an offer ... shipping in the UK is about £25 with UPS which is amazing because this thing is big and heavy!
Lee.
