Static electricity: Unique to Vinyl Systems?

There's probably no need to reinsert the old equipment. I think you are saying that the popping and clicking sounds you heard with that equipment while playing a record were very similar to what you hear now with the new equipment when no record is playing. Which answers my question.

But given that you've been using a 47K load impedance, and I assume you were also using that impedance with your prior cartridge which I take it was a moving magnet, I would definitely make the 100 ohm experiment the next order of business. There are multiple reasons why that might help.

A noticeable hum in the phono when not playing could be eletromagnetic interference (EMI) caused by nearby power transformers. I had this problem recently caused by nearby outside air conditioning/heating units and other nearby electric devices with power transformers. Proximity of phono/pre-amp to power amp transformers is a common scenario for this. The solution is to add distance from phono gear to any nearby power consuming electric devices. Pops/clicks could be related to this, but not sure. The hum itself is a clear problem to address and see what happens.

In my case, I was able to eliminate the hum completely by placing my low level phono step up pre-amp inside rolled up mu metal foil and adjusting the location somewhat. Mu metal foil is inexpensive and designed for this purpose.

In any case, look for nearby devices with power transformers and try adding distance between your phono section and that device and see if hum level decreases or changes with location. That would at least help identify the source of teh problem. How to resolve from there would depend. If the phono pre-amp is integrated into the same box as other amp componenets, it could be an inherent problem or design flaw that would be tougher to resolve. I do not recall if you use an outboard phono pre-amp or a phono pre-amp built into a pre-amp or integrated or receiver perhaps?

Here in Minnesota, it can get pretty dry in the winter. But I never have pops from the turntable- ever.

To me it sounds like a bad ground so let's try a few things and see if I am right.

First, disconnect the tone arm cable from the preamp. Do you still get the ticking/popping?

If yes => problem with preamp. Bad tubes, bad ground or bad cable.

If no => the first thing to do is investigate how the 'table and arm are grounded. If the arm and 'table are not grounded together then you have your first place to look.

Let us know how things go.

Richard,

Sorry I just realized reading that the hum is no longer an issue. EMI is likely not the concern currently then.

Tube issues in the phono pre would seem a likely suspect. Tube tolerance in a phono section can be problematic and only the highest quality, quietest tube or tubes are needed for best results.

If the phon pre-amp output can be run into a different line level input on the pre-amp or whatever device the phon pre is feeding, that would be an easy and worthwhile test.

Also, be sure that the phono pre-amp putput level is properly matched to teh pre-amp input. You would not for example want to run a line level output from a phono pre-amp into a lower level (than line) phono input on a pre-amp, for example.

Al, the previous mm cartridge was used with a different phono stage, not with the Jolida. It was used with PS Audio phono, which doesn't offer as many choices as the Jolida for cart settings, basically a mm and an mc setting. The PS Audio and the Rega P5 with a mm cart worked well for a while, but the phono developed the hum after it was off warranty and the manufacturer hasn't been helpful (basically telling me not to send it in for a repair).
In the meantime this other noise developed, well after the hum developed (I was tolerating the hum for a couple of years, most of my listening is digital anyway). Ultimately I decided to uograde my vinyl and first added the Clearaudio
mc Emotion cart and tt. The increase in low level detail pushed me over the edge for tolerating noise from the phono, and I was interested in a tubed phono stage. I've had a tubed linestage preamp in the past, so I know what the background sound of tubes is, but this noise, which was present on the old phono stage, is clearly different.
I live in Chicago, about 4 miles from the Music Direct Outlet. I picked up the Musical Surroundings Nova Phono stage earlier today. This is solid state but battery operated. The battery is charging at home now. I'm hoping that it is less prone to RFI. If not, it goes right back. If it is quieter, then the Jolida, goes back.
Mapman, I'll try running the Jolida into an AVR in my surround sound system, just to see what background noise is produced. The AVR is in a different level ofthe house, so that could be a different RFI zone, which is another variable...
