Wow, a 9-40? I'm jealous! Those things are so darned cool- I know they eat records, but I wish Brunswick had an equivalent.PeterF wrote: Sat Mar 05, 2022 8:18 pm Well, I learned a lot about these things today!
I was able to find the replacement part from George Vollema, and ordered it. Then I dremeled and chipped the old piece out and degreased the whole messy thing. There are 5 ball bearings in there so be careful when you do that.
The insert/hood part is essentially impossible to remove non-destructively. I opted to replace rather than repair because it was pretty cracked already, so I figured I’d just get it over with. Also it’s for a big 9-40 with that two-headed tonearm, which has the extremely heavy horseshoe magnet pickup AND an orthophonic reproducer cantilevered out at the end of the arm.
There are two sizes of back brackets and at least two base units. You can find a base unit that works on your machine, but the alignment of the back bracket might be for a centered tonearm (directly behind platter) or for an offset one (to the right side behind the platter.
So my huntin’ dawg and I actually found a couple that would fit, but that were wrong.
Thanks everyone for the advice.
