MC loading at 47K
you might experience very thin sound and lack of holography.the realistic load impedance to try is sub- 100Ohms. You can solder 100Ohms resistor in-parallel with 47K resistor or try different resistors using aligator clips. 
Bi-Amp Mash Up SS on Bass and Tubes on top?
There are amps with variable gain mostly sold on pro audio markets so you can adjust the gain(in some cases sensitivity as well) of the amp in order to match parameters of the trebble amp. 
Bi-Amp Mash Up SS on Bass and Tubes on top?
you'll just double the power. more is almost always better. 
Help Diagnose Tube Preamp Problem
I don't think it's preamp. I think it's amplifiers. Tapping tubes isn't a good idea at all. 
Bi-Amp Mash Up SS on Bass and Tubes on top?
...only for small volume control ranges with large sacrifice to the dynamic headroom... The situation is really as follows: Let's say you'll pick up trebble amp with higher sensitivity. On low volume levels you'll hear more trebble even from less ... 
Help Diagnose Tube Preamp Problem
Did you check bias?Tubes that are out of bias deeply might not be good anymore and certaly can pick up microphonies. If the amp is new and tubes are deeply out of bias or you shouldn't bias these amps at all(have manuals?), you should contact the ... 
Volume control vs. attenuation control
In your case you're describing gain control vs. attenuation control on your preamp section that should be set to the best possible volume range that you want to operate your volume control for ex 7...12 o'clock. If you feel that you get distortion... 
difference from higher input impedence on amp?
Agree to Ahendler. 
How do I know if iTunes files are all 'lossless'?
I'm not sure if iTunes plays lossless files at all such as EAC, FLAC etc...?I use Media Monkey since I couldn't uncode them with i-Tunes.There's certainly hi-rez capability of iTunes but still not considered lossless. 
Calculating total capacitance
The total capacitance adds up in your case if you find out the cartridge capacitance.From ballpark estimate point I would increase the load capacitance if adjustable. 
MC Cartridge Degaussing Demagnetizing
Dude MC cartridges should be ALWAYS magnetized and NEVER demagnetized. As simple as that. 
preamp - price vs age
For me it's worth. I usually tax the same amount if I pick up equipment to fix or to service (mainly studio gear and live sound) 
Humming/Buzzing from Pro-Ject Speed Box II....
if it's still on warranty, you can replace it. they might have ground path problems. 
Self-powered speakers: any good?
The champ of all self-powered speakers I've ever heard are Event Opal. Event company is mostly oriented for pro audio near-filed studio monitors but Opal has truly high-end performance for the price paid. They're self-powered with over 400 continu... 
preamp - price vs age
Finalize your work with resoldering all joints with fresh solder if you're savyy.
