| Using battery power to go off the City's power grid @jollygreenaudiophile2 mentioned a flywheel type system. Just in case some of you wanted to take a look at this type of energy storage system, here's one that I'm aware of (BTW, you can click on the link on the right hand side for a tutorial): ht... | |

Many models include metering too. Here's the thing abou... | |

| Intermittent low hum/buzz >>>You have to put your ear right up to the speakers to here it<<< @bikeboy52 Just wondering if the noise is present, *equally*, in both the L & R channels? >>>Tubes are noisy. They just are. I’ve tried multiple se... | |

| Star Grounding I agree 100% with mrderrick. What he's basically describing *is a* star ground system. You probably already have most of it established in your house right now. I'm a retired Radio Broadcast Engineer, and I had broadcast towers (that were right ne... | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? So to be 100% sure Filip, while in your apartment, using a SS phono stage (for example, the CP60), and the turntable connected *to the* CP60, the noise goes completely away? Is that correct? if so, I kind of agree with audphile1: At this point,... | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? >>>So I took the EAR to my friend's place. Horrible wiring, cheap components - absolutely quiet and great sounding.<<< I'd be curious in knowing if his system has the same meshing of XLR and RCA equipment as yours does, or is hi... | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? It also sounds like you purchased the EAR used, and I'm wondering if anyone has made some internal modifications along the way. | |

This is when ground loops can take place. Are you ... | |

| Tube PHONO preamp interference - RFI, EMI, bad grounding? So to be 100% sure, in your current high RFI/EMI environment, using a SS phono stage (the CP60) produces no noise? Is that correct? ...when using the exact RCA cables you were using when hooking up the EAR? | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? I just noticed this: >>>solid stages (I had 3, they were ok)<<< So to be 100% sure, in your current high RFI/EMI environment, using a SS phono stage (the CP60) produces no noise? Is that correct? | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? Sorry, I didn't realize that the LS16 didn't have an internal TT preamp. Is there any TT noise when going into the CP60's TT input (using the existing RCA cables that you're using with the EAR setup)? |
