I believe CJ makes a comment on their web site concerning tube life on pre-amps. So you may want to do some purusing there. But basically I think they comment that pre-amp tubes should last 2 to 3 years under normal use.
As far as purchasing tubes. I have had good luck with the Tube Store and Triode Electronics; both have a web site you can order from. I have also purchased tubes from Conrad Johnson and as Sugarbrie suggests they are not the cheapest but if all you want is stock tubes they are a very good safe and reliables source.
Thanks, Chuck
