This is fascinating [to me]!
I just transferred Edison Diamond Disc #82236-R (Songs my mother taught me - Dvorak & Poem by Fibich-Kubelik)
When I recorded it in stereo and then merged the two channels and declicked, the noise was still unbearable.
This time I used the 'Y' adaper and recorded it in mono - night and day!!
I'm starting to see that each record side has to be tested both ways.
The record I transferred before this one was the opposite.
Sometimes recording it in mono is better and sometimes recording it in stereo is better.
I will do the declicking afterward from now on.

For myself, I do not "Declick" or run any noise reduction before combining the channels (which I do on the computer, not from cartridge wiring). The reason is that you want as much noise as possible to cancel when combining the channels. The noise that is going to cancel is in both channels but with opposite phase. For example, although a loud click may be louder in one channel that the other, the less loud one will still be the corresponding "negative" that will bring down the louder one in other channel, even if not completely. And a number of such "pairs" are equal in strength, or close to it. Anything you have done to one channel or the other with a computer program will interfere with this cancellation process, so combining the channels should be done first. The same is true for ordinary groove wall noise in a mono LP, much of which will cancel itself out when the channels are combined.
The reason not to wire the cartridge to mono is that sometimes one channel (groove wall) is a mess while the other one comes thru OK, and you want to be able to access the good side to assemble to best result. If you have already combined the channels, you have put the mess in both channels already, where you can't pull the channels apart. So I keep an original "stereo" version on the computer, even though I am working on the one where the channels have been combined, in case I find that I need it.
