New Tubes

I just purchased a used Pro-Ject Tube Box DS2 Phono preamplifier.

The tubes have about 500 hours. Does anyone who has own this

preamp have any suggestions on upgrading the old tubes ?

They are capable of 5000 - 10,000 hours. I had 60's Fisher tube gear with the originals still installed, working and sounding fine.
