Low Voltage Tubes

[Jaicen_solo]

Hey guys, I was wondering if there's anybody here from the UK that knows where to source a 12U7 and a 12K5 so that I can build a mini-champ??
The design is from this site:

I can get them from the US, but I don't want to pay for or wait for the excessive shipping!  
Thanks!

Thanks,
I've tried them but they only seem to sell the standard high voltage tubes used in guitar amps. Anybody got any other ideas??

Anyone know what the lifetime on these tubes is? I would expect the preamp tubes to have a long life, but what about a low-voltage power tube?

Jaicen_solo,
    You can find some funky tubes on ebay quite often. You might keep an eye out there.
