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??

As I recall, the original cartridge used in the Wurlitzer 1050 is the Shure M44-C. The stylus ( needle ) is N44-C. The color of the stylus grip should be robins egg blue ( other colors have different specifications which should be avoided for your use ) . Manufacturers stylus pressure range for the N44-C is 3 to 5 grams, Optimum for jukebox use was 4 grams. there may be some budget priced ' tone Arm pressure guage ' available as in recent years records and turntables to play them have made somewhat of a comeback. Here is an example:

Although not an original Shure replacement needle, the one shown in this pic approximates the color of the N44-C needle which is as I remember the Wurlitzer 1050 was equipped with when they were new. We had about 12 of these machines on location when the 1050 was still a commercially viable machine..
