Regular Singular Points

I was searching through the basement again (I find the damndest things down there) and came across a collection of electronic tubes that I have acquired over the years. I have some tube equipment and I’m a big proponent of the technology, but, realistically, I’m never going to get around to using these old components and they really need a home. Most of these tubes are basically useless. How many people are going to find a use for Amperite 3-15 Automatic Regulator Ballest Tubes or GCDBGA TV sweep tubes? Someone will correct me if I’m wrong, but audio amplification is currently the only use for tube technology. That said, I have to mention that in this collection of tubes is a set of 4 Telefunken 12au7′s (Know as ECC82′s in Western Europe). They appear to be perfect, and possibly matched. Hard to say when it comes to tubes … it’s not like the old days where you could bicycle down to the Radio Shack and plug them into the tube tester. I have a GE 6L6GA still in the box, too, but these are normally used in pairs so having one isn’t such a big deal. 12au7′s, however, are used in all sorts of pre-amps and I think I have about 12 of these, with the 4 Telefunkens being the most valuable. Here’s some possibly useful tubes I found:

Raytheon CK5814A Twin Triode Amplifier/Oscillator (4)
GE 6087/5Y3WGT (2)
GE 6J6A (ECC91′s) (4)

Some rectifier tubes:
RCA 6X4
GE 3A3
GE 5U4GB/5AS4A (2)
Raytheon 5U4QB
Dumont 6DA4A

Does anyone want them?
