The BSR UA-15

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.

Good work, Mr. Mogul. This BSR came from the Silvertone?

Yes, Bill, from the Silvertone 6090.

The styli came today from Gary !

I'll test the cartridge soon.
