For tube pream you should try to find CAT JL1(might or mightnot have phono). It's the ultimate tube unit that hard to beat at 10x price to pay.
If you need MC phonostage I'd recommend choosing solid state. High gain tube devices are noisy in general. One of the best contenders I know of is Violectric(violectric.de). This phonostage will have two analogue inputs one is balanced and another is unbalanced. For the balanced connection all you need to do is to convert your unbalanced tonearm to 5-din connector where 4 dins are for +-2ch and 5th is ground. For the unbalanced connection you need to speak to manufacturer(they're quite flexible customizing their product) to install toggle switch between two inputs so you don't run them at the same time.
Having in mind that you listen computer audio, there are excellent choices of multi-format USB-DAC preamps that do the great preamp job with high quality volume control such as Antelope Audio Zodiac, Burson etc... Meaning you can also have DAC-preamp with external phonostage for your rig.
P.S. Dont forget to click on UK flag once you get to violectric.de if you don't speak/read german:-)
