Tubes?

I'd stick to Albert's advice. It is sound, I think. Give us a list of what you have, wait for responses and go on from there.

+1 for Mr A's advice. Further- The majority of musical instrument amp repairmen own tube testers, as tubes are widely used in music/sound gear. Check your yellow pages, and make a couple calls.

Thanks for the replies so far. Here's the list of tubes. I had no idea how to sort them, so I just did it based on external appearance, then by alphabetical order on the designation.

Edit: the preview seems like it won't be quite readable, so here's an Excel version: http://dl.getdropbox.com/u/243/Tubes.xls
