Advice for newbie on Tube gear


I'm seriously condsidering getting into tubes (valves here in UK).
I saw & heard them once at a hifi show & have been fantasising ever since.
I'm a bit tech illiterate.
I've been offered Sonic Frontiers SFL-2 preamp + SFCD-1 CD player (240V) for US$2200. Cond is v.good, tubes are about 18mths old. I'll probably buy an ss power amp also(below $700 used).
I'd appreciate any advice on what I'm letting myself in for :
How difficult is it to find & change tubes , How will I know when tubes need to be changed , How much will it cost , What else will I need to do (biasing???, capacitor replacing...).
Are tube SF units low maintenance? I don't really have much spare time ,and am easily confused by techy things.
My system : nothing left apart from AQ Diamond X3 i/c's, AQ Sterling spkr cable, and an old pair of excellent highly sensitive (96db), hi-end(ish) French speakers - Helius Sirius II (only a few made in the '70s/'80s).

First, you need to know that there are two completly different worlds in the tube universe. Single ended and Push pull. They are so different that you would never believe it unless you heard it for yourself! I do not want to give my strong oppinion about the differences here but before you buy anything please listen to both. Your oppinion is all that matters. For a great site to read up on this topic look at the triode guild site- just do a search under triode guild.
"I'm seriously thinking of getting into tubes" "I'd appreciate ANY advise on what I'm letting myself in for" Sounds like a general question on tubes to me?? Mabe my response should be go ahead and buy this stuff- you might like it, you might not but thats ok, it's your money not mine. I say go for it! Ya right. uhg
