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

:) I just got home from a somewhat unsuccessfull fishing trip to Charlevoix and you guys have kept going on this thread and I found it's even in those three threads right on top. How did it get there? Really didn't plan on that.

Still don't have the amp as I need to wait how the whole GM thing will play out this week as unfortunately I work for a company which is directly affected by that. Hope I won't be knocking on the door of the unemploment office downtown next week.

Well, I shall keep coming back as I kinda like a thread with it's own heartbeat. As far as the usefullness goes I guess it has outlived it a little, yet if we were to no never through in something a little different this could be a somewhat boring forum.

Thanks guys
Krauti, GM as well as some other major car manufacturers are very capable of building some of the worlds best vehicles but it is a terrible shame that top management failed to make the transition from gasoline vehicles to greener transportation. They had plenty of time to contemplate this years ago. Global warmer is a serious threat and if we continue to on the path were on, no one will be employed. Will be too busy trying to survive.

Anyway there is a downside to everything, both solid state and tubes, just pick your poison.
Kruati, I bet next time you'll phrase your question differently. ;-)

98% of this thread is complete nonsense, but Phd's last post really took things down the crapper.
This thread has outlived it's usefulness and as Dan_ed points out, it's definitely gone "down the crapper" with Phd's asinine remarks. Maybe we should all scrap our inefficient gear and go with class D amps to save the planet. NOT!
When did this forum become so mean spirited? I can't rememeber when we've seen so many personal attacks in one thread. It would nice if we could return to succintly responding to queries and approriate discussions without the personal afronts. Perhaps those that feel the need to lower the standards of this type of dialogue should frequent that other site?
