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).

Mahandave, maybe it was a general question on tubes. Issues on changing/buying tubes + biassing were answered, as well as other suggestions. I didn't find those specific comments/explanations elsewhere. Opinions were welcomed - sarcasm was not.

Viridian has it right, and the SF components are well-regarded, so I think your decision to go for it will prove fruitful. If your previous SS digital source and preamp were on a par with the $700 SS amp you propose to buy, than I suspect that the SF gear will be much superior. If the pair was retubed only 18 months ago, you won't have to worry about new tubes for at least that long again (barring a faulty or damaged tube). Enjoy your new gear!

Your choice of a preamp is fine - very high quality stuff and should last a long time if its in good shape. You mentioned the SF 80 tube amp. I have had one in a second system for the last 8 years - this is an excellent choice for the prices i see them going for on the internet. The choice of small tubes and power tubes available will allow you to dial in the kind of sound you want from detailed to warm. Its an absolute snap to bias new tubes and is good for a beginner to expirement with. Good bass - lots of power. Sounds more typical of older tube amps than the later models. However, be sure that you have a good local repair facility - if you need service you don't want to have to ship this to canada. Enjoy...
