DIY TT
Holmz, just buy the SOTA Eclipse package complete. Does it occur to you that the question “ where do I buy a DIY platter and bearing?” Is internally an oxymoron, since DIY implies you want to make those items yourself. Raul, I have no conviction ... 
Mono Cartridge Question
I am sure one can convert a Jubilee to mono, if its internal works are like those of the London.  
Mono Cartridge Question
Ortofon mono cartridges are usually stereo cartridges where the two channels are internally bridged, but their verbiage is typically ambiguous enough to allow the reader to believe the cartridge is true mono. So “coils” (plural) is probably accura... 
Balance control?
The trim pots in the Herron might alter plate resistance on the input voltage amplifier tubes, which would affect gain. In my opinion most audiophiles would get in trouble fiddling with such a parameter. Or they may operate in some other way. Rega... 
Will this stuff ruin my records?
Here we go again. Please read Antinn’s discourse on why not to use Dawn or any other commercial dishwashing detergent.  
Mono Cartridge Question
I respect your opinion, because you’ve tried it both ways.  
Will this stuff ruin my records?
If it smells like dry cleaning fluid, dump it !!! Dry cleaning fluid would likely damage vinyl. Then read the thread on cleaning vinyl properly. In my VPI I use distilled water containing Isopropyl alcohol up to 25% plus a few drops of Triton X10... 
Mono Cartridge Question
Which is why I asked the question. The difference between using a mono cartridge vs a mono switch is that in the first case the mono signal is derived before loading, RIAA correction, and amplification. Whereas using a mono switch on a linestage o... 
Mono Cartridge Question
All of you guys who extoll the virtues of using a mono cartridge on a mono LP, do you have a mono switch on your linestage?  And if so, do you hear a difference between the mono switch used with a stereo cartridge vs a mono cartridge?  My opinion ... 
SUT - electrical theory and practical experience
Raul, with regard to your question above, who is “Palmer”?  Anyway I hope I conveyed my opinion that current driven phono stages are not categorically better than voltage driven ones. They’re just a novel approach to an old problem. Again, in my o... 
Lyra Etna Lambda SL tracking force
Search these archives and the internet on azimuth. There are good arguments to be made for simply setting the stylus tip perpendicular to the groove, regardless of electrical measurements.    
SUT - electrical theory and practical experience
The point I was trying to make when I pointed out that transimpedance phono stages generally are just voltage driven stages with a current to voltage converter added on to the front end is that they are subject to foibles just like voltage input p... 
System that sounds so real it is easy to mistaken it is not live
I fully agree that TL bass is not suitable for your particular goal unless you have room for truly massive cabinetry. I’m getting what bass  I want with what I have. You ignore the fact that I used HDF, not MDF, and that the cabinets are further d... 
Checking Anti-Skate?
Eldartford, skating force increases with increasing VTF, because skating is caused by friction between stylus and groove. so the desired amount of antiskate also should increase accordingly. Increasing VTF is certainly not the cure for the skating... 
SUT - electrical theory and practical experience
Also, in a voltage driven conventional stage, the input load R can be thought of as the simplest form of passive current to voltage converter.
