Tubes Asylum Questions about tubes and gear that glows. FAQ |
|
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!
