Tubes... what do they do?...

Thanks Paul. I also found this doc to be useful as well, back when I wanted to research the anatomy and function of a typical SET amp. This also includes many of the scientific strategies and practical analysis of the tube amp, which also produces tangible conclusive results.

I must admit, even though I'm not a fan of tube amplification, this document was very eductional regarding the practical applications many of today's tube amp manufactors use to test their products before release to the market.

This is just one of many available. I'll see if I can find more and post them.

I'm glad to see there is more than one person who is into education regardless of how much experience one has.

Good looking out Pauly! : )

Enjoy!

Its amazing whats available on Google.

Here's another good link to review.

This covers both arguments, so to speak.

Don't wanna be a pest about things but here's another.

CD Wallace – apologies for my tone in prior post, it was uncalled for.

The article you posted pertaining to the CAD300SEI is spot on. I always cringe when folks want to show me test results to prove how good their sound is … my ears have rarely been able to match their test results.

The hobby wouldn’t be much fun if there wasn’t things to learn.

Slightly off topic. I spoke to a gent name Peter Ledermann of Soundsmith (http://www.sound-smith.com/cartridges/sg.html) . He has just developed a brand new type of electro mechanical cart that does not make use of coils or magnets. If what he says is true, it will be a paradigm shift for analogue folks … Yep, there a lot to learn and a lot of new things audio.
