ID these tubes

[Valvehead]

Just pulled some 6550's out of an older Ampeg bass amp. The lettering on the side says " Electronic Tube" made in usa .

what brand are these?

worth anything to the old school tube lovers ?

what do they look like? A picture would help enormously with tube ID. If it's a coke bottle, then Tung-Sol. Straight sides with sort of gold splattery welds on the plates, then Sylvania, if not prob'ly GE.
