Is there anything inherently better about the shape and number of getters in a tube, or is it's getter type (i.e. DD) indicative of other qualities inthe tube? A getter's purpose is to capture stray gas molecules in the tube, right?

Tube world has nice tubes www.tubeworld.com brenden is a bit pricey but you get very good tubes and he stands behind his sales (something that is important is vintage/NOS sales IMHO). I like the new EH offerings for EL34, check out www.newsensor.com (the owner of sovtek, EH, svetlana, "mullard" and "tungsol" brands) regards, tony

I am with Tony on this one: a reliable dealer is indeed worth some extra financial outlay and tubeworld struck me as being reliable.

For EL34 I'd also consider Valve Arts. I am very pleased with the tone of my cryoed quad used in a Maratz 8B: nice and creamy would be my description.
