Siemens D3A tubes...

Looks like I'll be coming into a set of (maybe) 8x of these Pentodes.

Is anyone interested?

    I like pretty glowy things. What are they used in? Any, um, yeah, I'm $ interested.

  • Ya know- I did a brief search, and it looks like they were used in some phono preamps, but that can't be the only use for a Pentode. I saw a listing for 10x for sale for $130, and that was seen as fair. They are no longer made.

    I don't have them yet, so we'll see when they get here.

  • Gain factor of 77. I'd guess that's why they were popular as phono preamp tubes.
