There is an auction http://www.ebay.com/itm/290922533510 (not mine
auction) where yet again seller states that the tubes are NOS. This
auction tripped me to finally come over my embarrassment and ask:
Could somebody explain me how the discoloration around cathodes is
supposed to appear during the tube operation? I understand that the
common knowledge is that only used B7971 have it. The new ones should
have a uniform back-plate.
