Help finding a fuse for sony str v45 reciever.

Hold on a bit. If the power supply fuse blows, this could indicate something is very wrong, usually that the output stage has melted. If it's a speaker fuse, it's slightly less alarming: someone might just have shorted the output. But sometimes fuses just go.

It's old I just got it from an estate sale. Worked fine for tuner and aux inputs but when I pressed the phono input with my turntable plugged in it the phono circuit blew the fuse. Thanks tho

What is your turntable? That sounds like an issue where you plugged in the speaker outputs of a compact stereo system. If this is the case it probably fried a bunch of stuff. More info - there are component turntables that rely on your preamp/amp to get the signal large enough to drive speakers and there are compact systems that contain a turntable, radio receiver and sometimes a tape deck along with an amp to drive speakers. These compact systems often used RCA jacks for speaker level outputs and should NEVER be attached to phono inputs.

It is a a sony ps lx 150h automatic stereo turntable system. Am I ok?

Looks like you have a proper turntable so that isn't the issue. Seems strange switching to phono would pop a fuse. Replace the fuse without the turntable connected and see if it blows again.

Thanks I ordered them from digi key. I just got both at an estate sale for a good price and want to test them

Is this your receiver? https://www.hifiengine.com/manual_library/sony/str-v45.shtml My first receiver was an STR-V45 bought sometime around 1984 from an adult friend after the tuner died. I had my late uncle fix it and I still own it even though I have better gear.

Just looked at the schematics and it says the power fuse should be 2 amps and not 3.15. Does it say anything by the fuseholder?


hairyanus47

Ya it says for continued protection against fire. Replace only with same type 3.15a 125v fuse.

This fuse is on a circuit board inside the unit if that matters

The blown one is 1 1/4 in. Long. The one amazon sent is 3/4 in. Thanks
