I have a working 1050 in the house. The tone-arm on this one has threaded adjustable weights attached in the rear, easily adjustable. The manual calls for what sounds like some expensive instrument dedicated to measuring the proper performance tone-arm pressure on the records, Needless to say, I don't have access to this.

Can anybody tell me, is there a simpler way to get somewhere in the ballpark of the required amount of tone-arm pressure before I start ruining my records??
