You are looking at three very nice NIB NOS RCA USA 6SC& double triode metal tubes, a predecessor to the 6SL7 tube. These are genuine USA manufactured tube in excellent physical and electrical condition. The white RCA print and production codes are very good, from batches RE2, K2E and V3. These tubes are brand new and unused, guaranteed not DOA. The boxes are also good. They measure as strong and well matched for current draw on our AVO 163 Mk IV -  Tube 1 - 1200/1260. Tube 2 -  1200/1250. Tube 3 - 1050/1000. New measure on the AVO 163 Mk IV is 1000. So, one very strong matched pair and a third as new tube.

Domestic shipping for this item is $12. Overseas shipping costs depend on which Australia Post destination zone your country is in.The charge stated in the invoice will be for Europe where shipping with tracking is $28 for France. Some destinations are more expensive than Europe - Russia is $34 and Israel is $36.
