I will put the Pre3/Phono3 back in the system and do some more checks.Nick wrote:You say on the WD site that you have sensitive speakers, but I am not sure what difference that would make as you would just have the volume turned down. How does the level of the noise (as I assume it is white noise filtered via the RIAA we are talking about) compare to the background noise of a LP?
Affordable but good MM phono stage.

Right, I've interrupted my snooker viewing and put the system back to normal.
Shorting the Phono3 input does not change the noise.
The record noise on the lead in is slightly louder than the main noise.
Pre3/Phono3 is a step up in quality from my other pre amp.
Now playing J.Armourplating and must admit it sounds very good. So, am I worrying unnecessarily about the "noise" ?

Thats got a healthy output, I would have expected that valve noise (and certainly resistor noise) would be inaudible with a phono III. Course if you turn it up it will be heard, but if its as loud as the vinyl background something is amiss somewhere.pre65 wrote:A Pickering XV15 -D625 moving magnet.Nick wrote:What cartridge are you using?

The background noise is without the stylus on the record or indeed without the tone arm plugged into the phono.
Or am I misunderstanding ?

I was asking how the noise of the phono stage (not playing record) compared to the sound of playing a record but when there was no music playing (should be easy to do with your collection).

Yes I understood what you were asking.
The surface noise on the record (without music playing) is a gnats louder than the background hash.
What is "vinyl roar" ?

It doesn't help you find a solution, but you certainly have a problem, the phono stage should not be that noisy. By comparison, I would regard that as too noisy with a MC cart into the phono and no step up, so I would gestimate that you have at least 20dB more noise that you should hope for.The surface noise on the record (without music playing) is a gnats louder than the background hash.

I will get them on the bench and check voltages.
As the noise is on both channels should I concentrate on the HT and heater supplies ?

It all depends on the "noise", I think you are describing white noise through the RIAA curve, if so the voltage will show nothing of use. The scope may.
FWTW, your original description of hash makes me think og a different noise, to me hash has more edges than noise, but that makes no real sense. At least no more than describing a saxophone sound as being like a carrot.
