Tube Matching Primer

Hi all. I'm in the process of rolling tubes for the new Cary 303/300 cd player and I am a novice in tubes. I understand from reading earlier posts that tube matching may not be critical in low power applications like cd players or preamps. However, I would still like to understand what matching is and what the numbers mean. Thanks in advance for your help.

Hi, Ozfly:
In all applications matching matters. Microphonics doesn't matter in CDPs, but does matter in pre-amp tubes. You want quiet tubes in your pre-amp. If you have tubed CDP, pre-amp & amp, suggest using very linear tubes in the CDP, and fine-tuning the output signal via pre-amp, driver and power tubes.

Hi, Ozfly:
Wish I could help you, but I don't know how to read the numbers. Hopefully, someone reading this will educate us both.
Best wishes,
Jay
