Advice Needed on Adjusting an Edison C-250

[Couch Potato]

I recently acquired a nice Edison C-250. I have come to notice the reproducer is rotated a bit as you can see in the below photos. It is that way even with other reproducers so I know it's the horn collar that is not quite aligned properly and am wondering how it might be brought back so it is more parallel to the platter/record. Has anyone else ever faced this issue and if so what steps did you take to improve it? Or perhaps I simply need to leave well enough alone. Thoughts?

The collar that secures the reproducer, circled in red in the photo below, is not in its locked position. You should start by rotating it until the pin marked with the blue arrow is all the way to the top of the slot, in the position marked with the green arrow. That may clear the discrepancy up by itself. Even if not, I suspect a 1/16" discrepancy will not make any significant difference in play, although others may have a different view on that question.

Well, thank you that is a good advice and an excellent reminder which led me take more observations.

The horn collar of course has a slot that the pin on the reproducer slides into and that slot actually affords some degree of rotation both clockwise (the direction I wish to rotate), and counter-clockwise (the direction I don't want to go). Based on you suggestion I carefully checked again by sliding the reproducer in and rotated it as far clockwise as the slot would allow and it evens out like I wish for since the slot in the horn collar affords that degree of "play" to do so with.

I think the fly in the ointment is that when you then go to tighten the collar down to secure the reproducer it naturally forces the reproducer back in the ill desired counter-clockwise direction and at that point the "play" in the slot works to my disadvantage!

It may be best for me to simply try to apply torque to the reproducer in the clockwise direction when tightening the collar in the opposite direction, hopefully with the result that the reproducer does not get tugged along with the collar in the same in the wrong direction. It seems to me that when you normally tighten the collar the reproducer pin ends up being forced down on the bottom of the slot and I wish for it in my case to remain at the top which the design of the collar works against.

If anyone else has a word of advice it would be welcome.

The other thing with this machine is I know how to lower and raise the horn assembly to adjust where the stylus bar rides in the reproducer loop. In my case I need to lower the horn assembly to adjust the stylus but there isn't much lower I can go before the horn will drag on the cabinet. I think my best course of action to counter act that is to simply to shim up the bedplate with felt or rubber as dyslexic genius recommends in one of his videos.

May I have read somewhere that you can also raise the position of the horn in the rotating axle? Kind of everything is indeed adjustable in the horn shaft... Or am I wrong?
