Help, No sound from Turntable

As suggested, I plugged my streamer into the input that I typically run the phono-preamp into on the Bryston BP26 preamp (the aux input) and it worked fine so that pretty much rules out the Pre-amp being the issue IMO.  

I took the cover off the Parasound to check for internal fuses. There are two and both look fine.  Everything on the Parasound lights up as it should.  

I've check all cabling.  Everything seems to be fine.  Note that one day it worked fine and the next without any change there was no sound.  

Not sure how to check the tonearm wiring or cartridge other than going down the road of trying to buy a cheapo MC cartridge just to check out.  

Appreciate all of the guidance.  I'll keep you posted on what it turns out to be. 

Best,

You can use a multimeter to check the wiring!

You might take the JC3 to a local store and have them plug it in to make sure it is working correctly. I never trust looking at a fuse. I always test continuity with a meter. It would be unusual to lose both channels of a cartridge or tonearm at the same time in the same way with out something dramatic happening like an elephant stepping on the cartridge.

What Mijostyn said. Fuses mostly do show a visible sign that they are blown, but you need to know what to look for. The most certain way to check the fuse is to check whether there is any resistance from one end to the other. A blown fuse will show infinite resistance across it. You mentioned finding some fuses inside the chassis. Without knowing anything about the JC3, that seems a bit odd, because fuses are typically mounted on the back panel below the IEC inlet or somewhere in that vicinity. If there is a fuse there, that is the one that would supply the audio circuit. In case you haven’t already done so, be sure to check that one.

Yes, I'm going to take the JC3 to my local shop hopefully next weekend to see what the deal is.
