The screws should be just tight enough to remove play. Any tighter is muffle the sound too.De Soto Frank wrote:Marco is quite correct in his observation about the locking-nuts being absent from the needle-bar pivot screws.
They will quickly loosen enough to cause "buzzing", "rasping", sounding like you're playing the record with a very worn needle.
( Good eye, Marco... I can't believe I didn't notice ! )
Hopefully locking-nuts from a later, more common #6 Columbia would work ?
This may resolve your reproducer deficiencies... If you can make it sound decent with the arm and reproducer you have, perhaps enjoy as-is.

Re: Question about Columbia reproducer
Hello
Following the indications to Bill (Lucius1958) I changed the aluminium diaphragm for one of mica and the change is spectacular.
The sound now is rich, full ranged.
Thanks to all for your help and comments.
Regards
Albert

Re: Question about Columbia reproducer
A change to mica was also going to be my suggestion, since I have a Columbia BII with the same tonearm, different reproducer, but mica diaphragm and it sounds great... Also, my reproducer does not have a metal cover over the diaphragm... That cover might affect the sound as well.

Re: Question about Columbia reproducer
If that metal diaphragm was original to the reproducer, it is possible that it was "tired" metal fatigued. That would cause it to be dead sounding. My 2 cents

Re: Question about Columbia reproducer
To the best of my knowledge, the Columbia Concert Grand reproducer of that period had a mica diaphragm. I believe that ribbed aluminum diaphragm was a later replacement.
