TUBE NOOB: WHAT BRAND

It's good to ask questions, but sometimes one has to try things on their own without the help or input from others.

Out of the four brands you mention, New Old Stock (NOS) Sylvania would be the better choice in my opinion.

What are you guys talking about? Some general advice for someone who knows nothing about tubes would be helpful. This is very unusual for audiogon.

1) I know some brands will be junk, a warning would be nice.

2) Do you have to match these tubes the way you do power tubes?

3) What specification will illustrate how a tube handles microphonics?

4) How can I test them electronically to make sure I am getting what I pay for.

This information would be helpful. Yes, I will experiment, but some guidelines would help make things easier for me. I would like to benefit from other peoples experience in this hobby, instead of spinning my wheels needlessly. That along with my reciprocation of knowledge is what this forum is all about. Besides what do I do, buy 30 sets of tubes and spend 3 weeks trying them all. That is just foolish!

Again, some help and advice would be greatly appreciated. Thanks in advance to those who decide to contribute positively to this discussion.

Try to identify what your trying to improve sonically before purchasing that special tube.

Do you want extended highs with much details and an even smoother midrange, or looking for a wider soundstage that you can almost swim in.

My choice, (in order) would be:

1. Tung Sol
2. Sylvania
3. RCA
4. GE
