Cleaning out the closet. A group of 3 EL34s that all test very strong on a 707 Dyna-Jet tube tester. As far as current draw goes, all are wildly mismatched to each other so these can only be useful to those with either a low wattage amp that uses a single output tube, those with an amp able to bias each output tube individually or those with a large EL34 collection that could potentially match these up to something already in their stash.
In my amp with around 505 - 510 V on the plates, the tubes are pulling the following currents:
Tesla Brown Base (center guide pin missing) - 46 ma
Siemens - 61 ma
Tesla Black Base - 78 ma
$115 USD shipped/PP or trade for some nice preamp tubes (European 12ax7s, certain others, etc).
