Members Stevenexp Posted May 4, 2008 Members Share Posted May 4, 2008 I pulled 5 of these out of my triple recto and I'm gonna swap them because I'm not impressed with the tone... the gain just doesn't sound like a rectifier and I think the preamp tubes are the culprit. It's loaded with jj 6l6 power tubes so I don't think it's them. Should I keep some in and only replace a couple? I don't really know what to do... Thoughts?

Members EdMan57 Posted May 4, 2008 Members Share Posted May 4, 2008 I find that most NOS preamp tubes work best in vintage amps and/or amps with a fairly simple and/or streamlined preamp circuit.I have several NOS Philips 12AX7A tubes and find them to work very well in Fender and Vox type amps,and not so well in Mesa/Boogies and the like.I think that it might have something to do with how cascading gain circuits compress and manipulate the tonal structure,rendering a NOS tubes "advantages" somewhat mute.

Members tuffvit Posted May 4, 2008 Members Share Posted May 4, 2008 they are a very smooth and creamy sounding tube not really for agressive music... Link to comment Share on other sites More sharing options...
Members Stevenexp Posted May 4, 2008 Author Members Share Posted May 4, 2008 I'm thinking about keeping 3 in and having a high gain jj 12ax7 in V1 and a balanced one in V5. Think that will make it sound better? Link to comment Share on other sites More sharing options...

Think that will make it sound better? Yeah,give it a shot,as the V1 position is usually the most critical tube for shaping an amp's overall tonal signature.

I ended up swapping it for a Chinese 9th Gen cos' the Legacy doesn't need any help being smooth Link to comment Share on other sites More sharing options...
