my tube experience (pre-amp mostly...):
*different tube brands do give tonal difference but at greater volume levels
*more tonal differences can be heard between rather than across types as oppossed to brand names. eg: 12AX7 vs ECC83

Personally, I cant agree more.
To me I cant really hear a difference. Maybe the clean sound is really good, thats about all. And that the overdrive isnt really strong, you have to rely on pedals if you want to play metal/hard rock.
Why would flicking the standby and on switch on at the same time blow the tube amps? Cos i always do that.
You kinda make me scared now. Lol

Ah, i see. So tube changes in the power stage will not really make much difference. I shall try other preamp tubes in time to come, probably a 5751 first to clean up the cleans a little and see how it works out. Good thing is dun need to bias the preamp tube. =) Oh, Sub! Do let us know how the ECC83 works for you, if you've swapped 'em already.
Cheers!
jiro, the standby switch is there so that when u on the amp u let the tubes warm up. if u immediately on the amp and start playing when the tubes are cold u strip the cathods off the tubes, meaning less tube life. if your tube amp doesn have a standby, just roll off the vol and thn on your amp and wait for a while before you start playing.
Also lets you keep the tubes warm inbetween sets too just leave the amp on and put it on stanby.

the power amp tubes do make tonal contributions but they require biasing (not all amps though) & it's not a plug-out/ plug-in kinda procedure, unlike pre-amp tubes.
i've been toggling between the 12AX7 & the ECC83 for quite some time now, i prefer the latter for a coarser distortion. if you like your distortion smooth & polite, the former would be a better pick.

Some older amps would overheat if you left it standby for too long, but I believe it's a result of poor engineering and cranking the amp too much. In general you shouldn't face such a problem with current tube amps.

the ECC83 is europe's interpretation of the 12AX7- they are essentially serving the same function.

Instead of tubes, let's not forget about cabs and speakers
These play a significant role in the overall sound. Marshall combos don't sound good as their head and cab versions due to the sound acoustics produced by the dimension, made of the cab etc. I once got a chance to plug my Laney into this huge Marshall closed 212 cab , which was the size of a 412 and boy oh boy it sounded like a different amp. Bass was plentiful, reverb was natural and the sound was less focused than a 112.
Between speakers and cabs, I'm inclined to say cabs are more important. Badly designed cabs will kill the sound of great speakers.

well there are straight or slanted cabs (usually the top half of a full-stack), open/closed backs make a big difference too, and not forgetting wood material. i think these are the main differences in cabinet (just talking about the enclosure, not even mentioning the speakers in the cab)

The 2 speakers are vertically aligned in the centre. Straight, not slanted. What you trying to get at?
