No.  You need:

A colour enlarger (obviously!)
A drum or slot processor (such as Nova).  You can use trays, but it means
fumbling in the dark for three process steps and is a bit smelly.  I used
to use a drum but got fed up with washing it between prints.  A Nova is a
lot more convenient, especially if you're doing a lot of printing.

Temperature control is not too critical provided you know what the
temperature actually is.  Nominal process temp is 24 deg C (= about 76 deg
F I think - someone will no doubt confirm!) so you can do it at room
temperature.  Before I got the Nova I used to heat my darkroom to 24 deg C
and wear light clothing ;-)  Temperatures from 22 to 30 deg C are fine.

There are three (plus a wash) steps to the process:
At 24 deg C, there is a 3 minute development, followed by a 30 sec wash in
clean water.
Then comes a 3 minute bleach, folowed by a 3 minute fix.  If using trays or
a Nova, you can turn the lights on once the print has been in the bleach
for 30 secs or so.  Finish off with a wash as usual.  It's possible (though
I've not tried it myself) to use oridanry b/w dev and fix.  It's possible
to get some contrast controil by changing the dev characteristics.  You
must however use the Ilforchrome bleach. AFAIK no-one's been able to
produce an alternative formula.

The processing's easy, getting the colour balance correct is not so easy.
If you're printing from Kodachrome, it's a lot easier.  Modern films like
Velvia can cause some problems with colour balance and contrast.

But - when you get it right, the results are wonderful!

Have fun :-)

Richard
