Purchased in late Oct from RAM - tubeaudiostore.com and used solely in BHK preamp. They have ~800 hours on them, >90% of their expected 10,000 hour life left. Very quiet tubes, nearly perfect. These are the LN version/rated. http://tubeaudiostore.com/am73go.html
They are sitting unused as I explore other tubes and they should be enjoyed.
Asking $140 for the pair including shipping to CONUS or I’ll consider a trade of similar value tubes.
