Oh, that's actually not a bad idea! The unit is a Helioprint PD 130. I
couldn't really find any info online, but I intend to check the bulb and
see if I can find that online. It would be great to continue using the
unit, it's so handy having the vacuum press and timer.

Heh, I wonder if I'm the one who burned out the bulb in the first place
from so much use :)
