To properly mount a phono cartridge, you need to be able to position it so that it remains tangent to the record grooves at all diameters. This is always a compromise. This gauge helps you to mount the cartridge to the headshell for the best compromise. This protractor is designed for records from 7 inch to 16 inch diameters. All other gauges are made for 12 inch LP records. Made from sturdy thin gauge cardboard. This instrument is cheap but accurate.
very cheap protractor
The protractor is printed on a really thin cardboard of low quality.
It came in a piece of cardboard that was longer than the box and then all crumpled.
I think the maximum value of the protractor is € 0.20.
You can download them better from the network.
I recommend the seller to make it downloadable online for free as a benefit for every online purchase.
