I would suggest demag'ing the heads every so often. Otherwise you will lose high freq response. Just make sure you use a demager with a protective tip and move the demager SLOWLY, you want remove magnetic fields from the heads not add them.
I demag the heads on my decks before doing any serious recording.
The stock load resistors on the 747 are carbon film. you may think the deck is quiet now at 7.5 ips, but wait til you listen to it with Vishays, you'll think you got 30% more musical detail coming through.
The other big benefit the 747 deserves is bypassing the audio stage coupling caps with film and foil caps.
Incidently the Vishays do wonders for MM and MC cart loading positions, but not trying to hi jack the thread.
