Hello Jim,

If the Svetlana tubes have good grids then we can repair them. If the grids are bad then we don’t rebuild them. We don’t buy Svetlana duds so we don’t normally have stock on Svetlana tubes.

As far as the Chinese duds go we can rebuild them but we don’t replace seals, ceramics or anodes on them no major work. So if they are new duds then we usually can repair them at least once.

If you have any other questions please let me know.
