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!!

I have no experience with tubes other than owning an Atma-Sphere  amp and preamp.
My suggestion is to PM Ralph Karsten (atmasphere). He would be likely to be able to help you discern what tubes are in your preamp.
Plus he's a nice guy who always tries to help out here on Audiogon.

And, I wish I could visit Stockholm.
