Available for immediate purchase is one (1) RCA 12AT7 (ECC81) twin triode TUBE/VALVE, made in USA. The  tube lettering is missing, the etched tube number is visible. 

The tube construction features Grey plates, with Small Halo getter. 

This tube has been tested on my calibrated TV-7 Mutual Conductance tube tester with a very strong, well-balanced reading of 72/76 where 50/50 is minimum and 77/77 is nominal new. 

This will be provided with an alternate box and will be well packed to ensure a safe arrival. 

Tracking is included in shipping cost for Canada and USA. Tracked shipping is not included for International shipments.

I am happy to combine shipping costs where possible.
