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).

Buying tube gear instead of transistor gear is like buying a horse instead of a car. The horse may be a more interesting means of travel, but it isn't as practical, and will take a great deal of care and patience on your part.

When I got into "HI-FI" everything was tubes, and you grumbled if a power amp cost more than a dollar a watt. Tube equipment needed continious tweeking...hum, microphonics, distortion...and the list goes on. If your hobby is fiddling with electronics, rather than listening to music, you will love tubes. Nothing wrong with that..I went through that phase myself. The "gassy" output tubes of one amp that I had began to glow, pulsating with the music with (strangely) little audible effect. It was so beautiful that I didn't replace the tubes for a long while!

Eventually I was happy to give up tubes, and be rid of all their difficulties. Solid state may not be perfect, but on balance I think its pros outweigh the cons.

If you do get tubes: (1) Yes tube technology is more appropriate for a preamp. (2) Get an old Dynaco power amp to play with. Don't jump into a multi Kilobuck (Kilopound)
power amp that you are afraid to tweek. You will learn more from the Dynaco.
