It is an excellent design. Upgrading the coupling capacitors, feedback loop capacitors and the resistors (plate, cathode, grid stopper and feedback) brings them up to the level of anything you can buy today in that poower range. 
Tube el34
My current favorite EL-34 is the Tesla EL-34LS made in Slovakia. 
Tube Amp Noise with Klipsch Cornwall II
Get the Quicksilver Horn Mono amps. No noise, no fuss and they sound great on high efficiency speakers.

Audio Research LS-7 LS7 upgrades suggestions
Replace the Rel-cap coupling capacitors (the yellow ones). 
Audio Research SP 11 vs Audio Research SP 16
The SP-16 falls well short of the SP-11 in sound quality. 
New Aluminum Platter from VPI
All I can say is, I'm glad I held onto my Aries 1. VPI has been more than a little schizophrenic lately. The 300 RPM motor was an upgrade, but its back to the 600 RPM motor for the Classic. Rim drive vs. belt drive; stand-alone motor vs. fixed mot... 
RIP J Gordon Holt
A legend in his own time. 
Which VPI platter would you choose?
The "new" inverted bearing is no better or worse that the original bearing. There is no theoretical difference in performance between the two. 
Great old speakers that are as good as new ones
Celestion SL-600 and SL-700

Groove Tubes EL34LS vs SED
I use the Tesla El-34LS in my Quicksilver M-135 monoblocks. They give the greatest "slam" in the low and mid-bass of any of the tubes I have tried (but I have never tried the Siemens). 
What Printed Magazine do you prefer?
HiFi + 
Audio Research Sp-6a-Should it be modified?
The best bang for the buck, and relatively simple to do, would be to replace the Wondercap metalized coupling caps with higher quality caps.
