I'd start with the USA importer if you are in the USA, next I'd contact a few premium tube resellers. A quick look on the web showed many choices.
Vacuum Tubes for Leben cs 600
Has anyone tried replace the 6CS7 and 6CM3 tubes in the Leben CS600. I understand the genesis for the CX600 was the shrinking availability of valves and tubes for the cs 600. As such I thought might be worthwhile stocking up with spares for future replacement. Well, there are not many out there. Has anyone had luck locating these tubes?
Thanks,
