"ALL HAVE TESTED LOW OR ARE NOT WORKING AND ARE BEING SOLD FOR PARTS OR NOT WORKING"

...and yet the current bid amount is $271? What?

And here all along I've apparently been pretty stupid to throw away bad tubes.** Obviously there's a market for dead tubes I wasn't aware of. Sigh.

** this does not include the tubes I tested for @Ripper2860 in the past and just claimed to throw away.

Hmmm..... how does one use bad / dead tube "for parts"?!

Thanks for the pics! The RCA and Sylvania are fairly run-of-the-mill kinda tubes (IMO). Nothing at all wrong with them and they probably will sound quite good, just neither are in 'holy grail' territory. I'm pleased to see (again, just my opinion) that the Raytheon is the T-plate version. That should sound pretty nice too. The flat plate version of the Raytheon is the one I hate...it's an ear-bleeder in my system. I'd be willing to bet that any of the 3 will sound better than the (new) Tung-Sol that's in your pics. Assume you got that from Schiit with your Lyr? It's not bad at all for an inexpensive and newly manufactured tube, but the ones you just got will quite probably be better. Be sure and give them a little time to break-in before coming to any conclusions.

Appreciate the response and insight! This is exactly why I am on Head-Fi!

Take it apart, recoat the cathode, and put it back together. Simple.

Would that turn a tube into a Franken-tube?!

More like a Broken-tube...

The hardest part would be sucking on it enough after reassembly to get a good vacuum...

Damn! That is a really cool video. Thanks for sharing! Looks like a bit of art and science, combined.

And it all starts with a Swiss army knife.
