[sdiy] Tube research

[Brousseau, Paul E (Paul)]

I was scrounging through a perminent flea market in Oakland (CA) yesterday, when I came across a couple of boxes of interest.  Both boxes were old wood, beautifully stained and very tarnished, dusty, and neglected.  The first one contained a vaccuum tube tester.  While this looked neat, I was more interested in the contents of the next box: around 15 tubes.  Most of them were RCA, all American, mostly small (~2" tall?), a few slightly larger (~3"?).

Now, I don't know much of anything about tubes.  But I bought them.  They are all legiably marked-- where can I go online to help me identify their purpose?

Given the purchase location, I have NO idea whether they work or not.  I didn't buy the tester, since I have no idea a) how to work it, and b) if its working.  (If anyone is interested, I can provide the address and you can check it out yourself...).  Where can I take these tubes, in the SF bay area, to see if they are working?

Thanks for any info!
