after opening up my scanner to tap the discriminator i am curious to know what the 2 black screw type looking inside a silver square box is.. there is what apears to be glue keeping them at the right place ....
also i noticed 4 smaller lil cirlces (silver in colour) that can be turned bearing RT2 RT3 RT5 AND RT6 on the PCB just wondering what they do?
thanks
