I have a 20s-30s Philco lowboy model 531. I want to get the chassis out but there is a toggle switch and a phono jack that has to be removed from the front panel first. The switch and jack both have round ring nuts with grooves like the edge of a dime. I can't get a grip on them with needle nose pliers cause they're slightly sunken into the brass control panel and i'm afraid i'll scratch the panel. Is there a technique or special tool to remove those nuts safely?
Thanks!
Thanks!
