Good informative post, Ariaaudio. As a musician, you should know that quiet tubes are an oxymoron for many guitarists, who PURPOSELY drive their amp output tubes into distortion! Tubes are know and selected for their distortion characteristics. No guitar player worth his salt will use a transistor amp because they won't produces that funky tube distortion sound without elaborate electronic circuitry which still will not give that same wonderful "chime". Thanks to guitar amps, the 6L6 (EL-34 substitute) will NEVER become obsolete and go out of current production! Thanks guys, and Happy Tunes!
More Questions about Tube Noise
If you will recall, perviously I posted a question about some noise form a pair of RT 12AU7 tubes in my CJ PV10A. (Thanks for the great info everyone, by the way.) I sent them back to the dealer and he found that one of the tubes was noisy and replaced both. I installed the replacements today but am still hearing noise of the tubes. Although, it is very faint and can't be heard unless my ear is within an inch of the speaker. The other tube is making no noise. So, my questions are: How much noise from a tube is acceptable? If a tube is noisy does that mean that it is 'bad' or not functioning optimally?
