The Talking Machine Forum — For All Antique Phonographs & Recordings

Hi Ron,

The height should be such that the limit pin on the repro weight should float in the center-ish of the bale it sits in on the reproducer when the repro is in the playing position on a standard diamond disc record. Refer to the section on setting the reproducer height in this thread: http://forum.talkingmachine.info/viewto ... ?f=2&t=476

Usually you don't have to ever adjust this. Besides the location of the limit pin, there is a worm gear that tracks the horn/tone arm that is engaged when the repro is lowered. You need to be aware of this as well.

Having said all this, are you sure that the linkage you created is the correct length? If it was too short it would cause the diamond tip to be held lower (while not allowing the repro weight to float) and I could envision that this could cause excessive force on the surface and cause the record to slow down.

Not being able to see what is going on makes it hard to diagnose. I would check the repro/weigth float when in play position. I would also check the linkage length. (A replacement diaphragm is not very expensive).

(Side question: Is the lacing you described the same as used to tie wire bundles in radio chassis? Sometimes called whipping? If so, that is what I would think would be the best if one wanted to make their own linkage).

Let us know what you find, or post some detailed photos.

Good luck and 73's

Brad,

Good move placing a link to the original Edison instructions. I know how to adjust this but it's very difficult to describe in writing without illustration, at least for me.

Obviously getting this right is critical for the machine to run properly and not destroy the stylus and records.
