Interesting.. I never knew it takes time for tubes to warm up....
Alwin, since you do not know much about tube amplifiers yet, I would HIGHLY suggest doing some real research on your own prior to buying, and not pay less attention to the whole SS vs tube rant that goes on here.
I have owned many types of amps over the years, running the gamut of what I could afford, to exactly what I wanted. SS, modeling, hybrid, and tube.
If you are not going to be playing out, and just recording, I would suggest really considering your application.
Are the recordings demos, or full fledge productions? Is the guitar the main primary instrument, i.e. Vai, Satch, etc, or one part of a band, insert rock band here, or a backing instrument ie. Brittney Spears? All these things should be taken into consideration, as the importance of your tone changes in each application
Secondly, do you have a decent mic set up? If not, a modeling pre amp might be the way to go. You can record whenever you want, and get decent tones down w/o bothering anyone
Price. I do not know if this is important in your situation or not. However, once again depending on your application, a expensive tube amp might just be overkill for what you might want to do.
Tone (subjective I agree)
responsive to ones playing
serviceable. If the fuse fails to protect the amp often the first thing to go will be a tube, which is replaceable.
Price for amp
Up keep. Some tube amps have to be rebiased everytime you change the tubes
Working on them can be dangerous if you do not know what your are doing. They have the ability to hold a lethal electrical charge long after they have been unplugged
Many are one trick ponies. (Have a great dist. but horrible clean, etc)
You have to be somewhat kind when transporting them
ease of set up (especially with some modeling amps)
some would say tone
Often have multiple options, effects, tones etc
easy to record direct (especially with modeling amps)
some would say tone
non-serviceable. When a fuse goes on a SS, some times all your left with is a big smoldering pile of goop.
a host of other subjective things like response, etc (which one could argue about tube amps as well)
This is by no means an all inclusive list of ideas, but shows that there is a lot to consider. My personal advice is buy some used gear, take it home and use it, and be prepared to do a lot of searching! Some of us are still searching after many decades! =0)
My personal opinion on the subject?
They are tools to help an artist with their creativity.
Use whatever helps you towards your goal.
90% of the time I use a tube amp, but I do use them for recording, and once in a while live use applications as well. Tube or SS, who cares as long as it does what you NEED it to do! Good luck on your search Alwin, and keep us posted! Later, Tobe
