WTB: CBS 12AU7 family tubes
« on: 2 Jan 2011, 05:17 pm »
I'm changing amps, so I'm looking for a nice matched pair of CBS (or CBS Hytron) tubes from the 12AU7 family, preferably 3 mica  :green:.

Also interested in other brand really good pairs in the 12AU7 family.

My current amp uses 12AX7's, and I have a number of primo pairs of these if someone's interested in a trade.

Thanks,

Randy

I have some used CBS Hytron 5814A tubes - 2 Mica BP - no idea of their history, I believe they were pulled from old test gear, not audio equipment - they test at 100% or better on my Jackson 648a Tube Tester, which isn't capable of determining if they are matched.

Let me know if you're interested.

Just spent a month collecting 12au7s, think I'm done for now.

Here's an ebay auction I was watching;
