The BSR UA-15
Posted: Sat Dec 24, 2022 7:25 pm
As I noted, this BSR is well-made, using the same
cam gear BSR kept for later models.
The idler was still good, something I find interesting.
Many 50 year old + BSR idlers still work fine.
The stylus should be in soon, weather permitting,
and then I can thoroughly test the original cartridge.
The curve-ball came after servicing all done and I
was playing a record album.
At the end of the album, the tonearm would not
pick up and return.
I knew the trip pawl on the cam gear was clean and dry.
I thought about how that trip pawl was engaged via the
hub on the platter.
I looked at the hub, and the projection that engages the
trip pawl.
The projection was really worn down for some reason.
Now, how in the heck to remedy that ?
Only other part to tweak would be the trip pawl lever.
So, I GENTLY bent that lever just a bit... and Voila !
The tonearm picks up correctly now.
