Pioneer QD-240 CD-4 Demodulator Fuses?

[quadnewbie]

There are 3 fuses inside that need replacing. They sat SOC 1A but they are old and I am not sure how many volts to put in or if they are AC or DC? Anyone can help? Thank you so much. I don't have a service manual.

I don't think fuses are rated by volts....they are on the same 110 as the rest of your house. Unless I'm mistaken the 1A refers to it being a 1 amp fuse. I'm sure a trip to the Radio Shack would get you what you need for those. John

The QD-240 has multi-voltage settings. Should be set to 120V for the US. We typically have 115-127V in the US, not "110V". Pioneer's setting of "110V" sets it to the 100-110V Japanese voltage. Set to "110V" will cause the power supply and regulators to run hot, and maybe fail. The primary fuse for a QD-240 is a 1A fuse for 110/120/130V, and .5A for 220/240V as per the manual. The two secondary fuses are 1A. 125V-rated fuses are fine, unless you are overseas with 220/240V, then use a .5A-250V rated fuse in the primary.
