When I had my Modwright 9.0, I used the Jan Philips tubes because they sound neutral, linear and smooth. I tried several and for the price, you can't beat it. I also agree that the nos Mullard rectifier tube sounded superb in the power supply.
If you want to tweak further, don't forget to get a nice power cord and I also found that it was very responsive to isolation footers. I liked the Vibrapod cones on the pre. They added more clarity and resolution. YMMV.
