Ron’s New System

[Audiohertz2]

You have one ..?

 

[microstrip]

I don't know. I experience anomalous and unexplainable phenomena.

Several 50 feet long single ended runs would be an easy explanation. Some people use similar size antennas to detect space weather and ionosphere effects.

Those solar flares were messing with my heart…no joke!

I believe you. It must be an unpleasant sensation.

I don't know. I experience anomalous and unexplainable phenomena.

I used to pick up some kind of radio signals with voices that would travel from speaker to speaker. Stereo! They wouldn't last long and I haven't had them in a while.

I always thought the Lawrence Livermore Lab would soak up and attenuate the grid at times. The system seems to sound better late at night, and when the weather is cold (air density?).

There are guys who try to hermetically and electronically seal and standardize their rooms with the usual array of power conditioners and environmental controls. I'm not sure that ultimately works completely except to treat the audiophile's worry warts. However, the audiophile will still have biorhythms and earth frequencies that can vary. Learning to roll with the vagaries of the grid and the body electric as standard cycles of nature might be the more peaceful solution.

Complete control over every variable is probably not possible.

For awhile, many years ago, my phonostage was acting like a radio receiver and I would get low level broadcasts from Russia or somewhere East with Slavic language. It stopped once I dealt with ground loop issues…

Me too… but after taking care of some ground issues too, it was gone. Never had a problem since.

Sounds like you are close to there?

 

[cjfrbw]

Pleasanton is a few miles from Livermore and the lab, and a lot of the employees and scientists live around the tri valley area.

Sounds like you are close to there?

Ron, I am not sure I follow your issue. Could you describe what you are hearing? If it is a ground issue, have you tried switching over to your second grounding scheme? I think you once told me that it was set up to be easily switchable.

Peter @PeterA ,

Why have a main and a secondary ground?
And why do you wanna switch in between?
I don’t get it… …

- I mean.. if the main ground system doesn’t work - why would a second one work, if it’s connected in the same house?

It’s not a main and secondary ground. My understanding is that Ron installed two different grounding systems when he was doing his house, renovation and listening room build out. I’m simply asking him if he has tried switching from one to the other.

Your question to me should be asked of Ron

Got it - Thanks Peter.

With phono, high frequency problems in the circut can alsothat you receiving radio Eriwan signals. Back then a pi inserted filters (capacity and coils) kill that signals. Amateur radio operators in the neighborhood can also cause something like this if they transmit with a lot of power (postal regulations are not followed)

Phono sections benefit quite a lot if they have RFI filtering at the input, even if you can't hear any radio stations!

LOMC cartridges generate RFI, anywhere from 100KHz up to 5MHz. Its caused by the inductance of the cartridge being in parallel with the capacitance of the tonearm cable. That creates a very highly tuned electrical resonance, exactly like that used to tune a radio. When it is energized (the radio parlence is going into excitation') by the cartridge tracking the LP, the result is RFI injected directly into the phono section. If it can't handle that, it will cause distortion, often perceived as brightness.

This is where the idea of a 'cartridge loading' resistor came from. The resistor detunes that resonance. So its really there for the benefit of the phono section, whose designer didn't take into account what can happen when a bit of inductance is placed in parallel with a bit of capacitance... So if you see a loading switch on the preamp you know the designer didn't take electronics 101 in college.

When the RFI is removed so is the distortion so the phono section behaves the way its supposed to. By installing RFI filters in the preamp you side step that whole RFI issue so its plug and play with any cartridge and no need to mess with 'loading' resistors. Of course, that also prevents the local FM station showing up too...

AM might also do it…

If the grounds are not the same, then one is on a higher ground.

Is ^that^ a question? Or ^a statement!^ ?
