I have a Yamaha THR5 10-Watt Stereo Desktop Modeling Amp and the toggle on/off switch is broken and i wanted to know what kind of switch i need because i did some searches on mini toggle switches and there are DPDT and SPDT 5 amp 120v and all kinds of different ratings for the amps and voltages for these. So does anyone know what rating and letter combo i guess lol i would be looking for?
