Which speakers will fill 5,000 cubic ft coherently
Unless I miss my guess, the output autoformers are essentially the same thing as using the speltz autoformers (which have different impedence multiplying taps), except that they are internal to the amp. So we are still back to the same issue; most... 
Which speakers will fill 5,000 cubic ft coherently
Davvie- But don't some Mac amps have internal autoformers? I could be wrong, but I think I read that somewhere. Denis- I think you should get the Selah's. I've always wanted to hear them and they are beautiful ;~) 
What are those extra tube inputs for?
bias adjustment 
Neutral el-34 .re-issue o/p tube for Jolida 302b.
Lenkspk- Were those JJs the "L" version (low noise, I think)? 
Tubes to solid state for amplifier path...
Class A SS is not the way to go, because those amps run hot at idle. 
Blue glow on preamp tubes - what is normal?
It is possible that there is an intermittent connection at one of the pins, that is making better contact due to thermal expansion, once the tube and socket warm up. 
Starting from scratch, passion for "steals"
Again, pls tell us your budget and preference for used or new. 
High Up or the Low Down with Tube Burn In
Not sure, but I think I may have read that the Mullard re-issues are not really anything like NOS British Mullards. 
Generic cleaning/fluid applicator brushes
One approach would be to use a soft paint brush and if you cook up a home brew cleaner (there are recipes on this forum if you search it), lay it on thick and let it sit for a while and then rinse, air-dry and test. If additional cleaning is requi... 
Component Recs
There are some AVRs that do good music and there are also many 2 channel pre-amp that have an HT pass thru input that allow you to integrate HT and 2 channel. If budget is tight, you may want to consider an all-in one unit like the Linn or Arcam D... 
Do I need a pre-amp?
Have fun, Pedro. Remember that your headphones probably have the greatest effect on the sound of your "system" and that some headphones have unusual impedence characteristics that make them work better with certain headphone amps. Read up on them ... 
New B speaker question
I have been very impressed with the Triangle Celius and next model down, forget which. They rock, they have good detail w/o being lean or analytical and they have good rhythm and bass. Paradigms are good but can be a bit etched with some equipment... 
Speaker Choice for Almarro 318B
At low to moderate volume, that amp is winner and should be fine with 89 dB speakers IF they have a relatively high and flat impedence curve. If you ever want more ooomph, you can go high eff. The Sequerras will not "knock you out" at first listen... 
Speaker Choice for Almarro 318B
Mb- Your room is moderate sized w/high ceilings. Not ideal for a lower powered tube amp, but with plenty of current from those 6cc3b tubes, you may be OK at 89-90 dB/w/1m. If you can find a used pair of the Sequerras you will never have a problem ... 
Do I need a pre-amp?
If you are not satisfied with the sound from the SCD-1/MF/Senn rig then I would get a better headphone amp or better phones. A pre-amp will not add anything. The Senns can be a bit laid back but to my ears they are very non-fatiguing and comfortable.
