What do you see as the downside of tubes?


I have decided on getting a tube amp and it will be the integrated Mastersound 300B driving a pair of Living Voice Avatars, so at least that decision has been taken.

My main question is what you see as downsides of having a tube amp. As I've decided on getting an integrated tube it's really about what the downsides are I might want to know about beforehand.

The ones I'm aware are the following.

-The tubes need to be replaced and in the case of a 300B this will be somewhat costly.

-Bias is another issue but I'm not sure how big an issue. Do you plug in your meter every so often or just when you roll tubes or replace a dead one? The meter as such isn't gonna be a big issue as I don't think it's that expensive.

-Heat won't be a big issue as we have no kids nor a nosy dog that could get burned. Hope my electricity bill isn't gonna go through the roof, but then again, I can't quite imagine that.

I'd appreciate if you could add whatever your experiences are regarding this question are as I'd like to know more before I buy it.

Thanks

What a great thread! I have been fascinated by tube amps for years and have never had the money or gumption to go that way,though the systems that I have heard have been magical.I am leaning more and more toward taking the plunge and going with a tube rig.I have a set of the original Snell "E 1s" and they should be a good fit for a tube amp or integrated.My main system has Acoustat 2s and unless I could aquire some serious big mono blocks would be a problem to drive.(If this is faulty thinking please say so)
The Dynaco ST70 and the upgrades/restorations available seem like a good starter path.Also I was thinking a tube preamp for the Acoustats might bring a touch of the tube sweetness I long for.
The Dynaco refurb route has a certain symmetry for me because I am driving the Acoustats with a Hafler 220,so I would have David Hafler's early and latest designs to compare a contrast.Also, it seems to me that since there are so many of them in use still that they must be doing something right.
The idea of tweaking and tube rolling sounds fun and interesting to me as well.Nothing is more fun than tweaking and discovering new magic in your system;after all,this is a hobby.
As for tubes going away in production;it seems that the Chinese and Russians are making them (military grade)in great number.(planning for Nuclear winter?)
Now if this recession/depression would just turn around,I could start shopping.:-)
