What tubes do I need?

Hello from Stockholm! I have a delicate problem. Bought a tube preamp a while ago -a french Audio Sculpture Ouverture (seemingly same company as Audio Matiere). The seller told me the two tubes are ECC83. I today bought two Siemens ECC83’s, but no sound at all (they light up, though...). This makes me think the original unmarked tubes are not ECC83. Maybe ECC88 or ECC82... Does anybody know? Is there an easy way to identify the original tubes? LOVE the sound of the Ouverture btw. Thanks!!

Put the originals back in and verify the amp is still operational.
Hopefully it is.
Then compare the tubes internal structure, size etc. While tubes of the same type exhibit many variations, it is possible to see enough similarities. See if there are any markings that might help with identification.
