© AP6.0This listing is foraQuad of Cetron USA - Made 811A Triode Power Tubes.
These are repackaged New Old Stock tubes with Richardson boxes.
They were carefully wrapped in the foam liners.
These tubes are absolutely 100% guaranteed operating as new tubes.
These are American Made tubes.
These would be perfect for that Collins 30L-1 amplifier, which requires the tubes to operate in a horizontal position.
Some modern import 811A tubes cannot operate this way.
I am offering a new benefit for buyers of any tube I claim as \"New Old Stock\".
I am offering the same warrantee that most original tube makers offered when these tubes were new.That means that my New Old Stock tubes carry a 90 full refund guarantee from date of purchase.If you buy a New Old Stock tube from me and it fails in 90 days or less, I\'ll either give you a new one if I have one or I\'ll refund your purchase price.
This is the best warrantee anywhere on vintage tubes!
TV Sweep tubes not covered, sorry, too much opportunity for abuse and damage.
Tubes physically broken are also not covered, obviously.
Also, any tube showing obvious signs of overheating (burned or melted plates, for example) cannot be returned.
I am happy to answer your questions but don\'t ask questions that I have already answered in the description.
