Members #6 Posted April 6, 2007 Members Share Posted April 6, 2007 power 1:1, but in terms of heard volume, i have read that tubes create a harmonic that gives a greater apparent volume per watt....anyone? am i full of it? i have a 20W all tube guitar amp that is far too loud....can blow the freakin house up....

Members Bluescout Posted April 6, 2007 Members Share Posted April 6, 2007 There is something about tube amps. My Firebass at 425 watts at 4 ohms wasn't as loud as a 300 watt SVT. I think it's in how tube amps break up gracefully. Also SS amp wattages may be overrated. Link to comment Share on other sites More sharing options...
Members bassman1956 Posted April 6, 2007 Members Share Posted April 6, 2007 Try a search. (We should have this FAQ'd by now.) A while back, a few of our amp pros went into significant detail about this. Link to comment Share on other sites More sharing options...
Members liko Posted April 6, 2007 Members Share Posted April 6, 2007 In both cases the wattage rating is usually continuous, meaning the maximum power before distortion starts. Tube amps start to distort earlier than solid state as they approach saturation. However, the difference does not become audible, and in fact is sometimes desired for its growl (while still considered clean), until beyond when a solid state amp would start distorting. It's the same reason behind why most guitarists prefer the sound of tube vs SS overdrive/distortion (unless you're going for the squarest wave possible for hardcore metal, in which case a solid-state amp is always going to chop the wave off more severely).

Members baracuda2004 Posted April 6, 2007 Members Share Posted April 6, 2007 I've heard that tubes can basically make it sound like your runnin an amp of 3 times the wattage of a solidstate with the same wattage, cause of harmonics and such. Don't know if that's true at all, but i'll tell you this. My Classic 400(400 watts tube) could over power a XXX(guitard 100 all tube) easily, I mean i would set my volume on 3 and he'd have his amp at almost full, and i've still got the original tubes from the factory(1999 I believe) in my classic 400. Sadly they're almost gone so i'm gonna have to get a full retube. I'm was blown away by my GK though so i'll never go back to the 400 for live sound. Maybe recording, but definately not live. After all that bitch is big and heavy. Here's mine Link to comment Share on other sites More sharing options...
Members Grumpy_Polecat Posted April 6, 2007 Members Share Posted April 6, 2007 A watt is a watt, but how you define it can be different. A watt is a measurement of power dissipation, nothing more, but if you define its value as peak power you get a different figure than you do if you rate it as RMS power. And then there's that whole tube harmonics thing... But a watt is still a watt. Link to comment Share on other sites More sharing options...
Moderators Kindness Posted April 6, 2007 Moderators Share Posted April 6, 2007 A watt is a watt, but perceived volume is another matter entirely.

Members Rippin' Robin Posted April 6, 2007 Members Share Posted April 6, 2007 What's a watt? A watt is a watt is a watt. A watt is 1 joule/sec. Cabinets can't taste whether the watts are tube or SS. Link to comment Share on other sites More sharing options...

Members baracuda2004 Posted April 6, 2007 Members Share Posted April 6, 2007 cause like all but 2 have this slight blue glow, and the amp has seemed to get pretty week and start to get this kinda hum/whistle thing that my ex-guitarist said happend when tubes are going out.

Slight blue is good. Red is not. The hum/whistle is hard to diagnose without hearing. It is possible you have a pair of tubes that need to be replaced. In general, a good set of tubes will last you decades. Link to comment Share on other sites More sharing options...

Moderators Kindness Posted April 6, 2007 Moderators Share Posted April 6, 2007 Do you have a good tech to take it too? A slimy one will take advantage of you and have you change all of the tubes. Link to comment Share on other sites More sharing options...
Members baracuda2004 Posted April 6, 2007 Members Share Posted April 6, 2007 there's a place around here that an old man runs and he's always been really good about things like that. It's also the only shop around here that carries Spector/Gibson and other high end basses + he's already worked on my amp when the original owner had it, my ex-guitatist original bassist.(he's known my friend/ex-guitarist Jay for a long time) Link to comment Share on other sites More sharing options...

Members Rippin' Robin Posted April 6, 2007 Members Share Posted April 6, 2007 It's not getting the tubes that's expensive. It's getting matched tubes that's expensive. A matched octet of 6L6s will set you back a bit Link to comment Share on other sites More sharing options...
Moderators Kindness Posted April 6, 2007 Moderators Share Posted April 6, 2007 True. It is even more "expensive" if you don't actually need 8 new tubes. Link to comment Share on other sites More sharing options...
Members baracuda2004 Posted April 6, 2007 Members Share Posted April 6, 2007 For a full retube I'd need 8 - 6550's5 - 12Ax7's1 - 12At7 I think i've looked before and it's between $200-300 depending on the brand of tubes I get. Link to comment Share on other sites More sharing options...
