'NOS' tubes are one of the bigger problems we have with our preamps. It is very difficult to find NOS 12AT7s that are as quiet as actual new ones. As with any high-performance tube equipment, you can't just buy tubes off-the-shelf and have them wo...

Atmasphere - I think you are too optimistic on the quality of the US power supply. The US grid is split into 4 quadrants and the supply agreements in place with the power providers have delivery standards etc, but there are NO standards in the agr...

I must have lucked out. I would not say the pressing is perfect, very few are, but it does not exhibit excessive noise on any particular track (including side 1); instead there a few random minor ticks and pops throughout- no loud crackling noises...

Then I am at a loss to understand. About 13 years ago I got the new Porcupine Tree LP Signify. Easily half of the pressings had defects. Unfortunately, this sort of thing happens...

However, he did also comment that with a true 3-phase AC synchronous motor controller (so you can throw away the phase-splitting capacitor), the Papst would have been MUCH quieter and therefore might outperform the Thorens motor in all other respe...

Pabst is indeed a company name and does not refer to a type of motor. The AC motor in our 208 is indeed the eddy current AC model and was also used by Rek-O-Kut and a variety of tape machines. With its external rotor, its flywheel effect is prodig...

Unsound, you used the phrase numerous requestsYour request for links which I provided does not constitute the above and my response also satisfied your lone request.So your statement above is clearly misleading.With regards to Norman Crowhurst, he...

Unsound, I have also outlined how anyone with modest test equipment can prove what I have said for themselves. There are even 'goners that have set up the test themselves and come up with the same conclusion. Check the archives; your statement to ...

'direct-coupled with transformers' has to be one of the more oxymoronic terms I've heard in a while.The term is 'transformer coupling'. To avoid confusion, leave 'direct coupling' out of it unless that really is what you mean.

Which Empire TT are you referring to? AC or DC drive ,belt type?The Empire is of course AC synchronous drive. But most of my experience with it is actually with our variant of the machine, which we have been doing since the mid-90s:http://www.atma...

I friend of mine had these for quite some time so I got to hear them a lot. At one point his girlfriend really put some pressure on him to get them out of the living room, so he had to look for replacements that were smaller and more 'appealing'.I...
