Svetlana 6550 Identificiation







I have acquired these and other Svetlana 6550's that were part of a RM9 amp purchase.

The vintage is marked '98 on the glass the boxes show a winged c --the tubes do not.

My understanding is the winged c logo came sometime after 1998.

These are unused & test new on an Amplitrex and are RAM tested and labeled.

What do I really have here? Thanks for any assistance!
