Hey, an old thread but thought I'd throw in my former and recent BIC experiences, FWIW...
Have never seen or used a stylus/cartridge positioning gauge with any of my turntables, so can't add much to that.
However, I recently came across a BIC 960 at a garage sale that I was able to rehab, and with a new belt, lubrication and stylus, it's working great.
Working on this jarred my memory, as I had owned a BIC turntable back in high school (in the late 70's). However, my BIC was nowhere near the quality of this 960, but as a record collector and struggling guitarist, I played a TON of records on it. I played it for years until the belt stretched out and fell off. I had no good way to get a new belt at the time so I replaced it with a direct drive Techics for a good price, as I was in college by then and impoverished!
As much as I had used that BIC back then, I cannot remember what model it was! I do know my old BIC had a smaller sized stamped platter, not the nice cast one like on this 960. I had a hard time finding one that looked like mine, and I now have to conclude that it must have been a 920. Based on Vinyl Engine, you wouldn't even think there was a BIC 920. Very little information about them online for some reason. Once again, ebay turned out to be a good source for research. A couple 920's on there, and deja vu all over again.
Anyway, that's what I know about BIC's. Like many TT's of that era the grease has turned to tar, so redo that, get a new belt, and rock on!
Take care, all!
