All Tubes Tested on 5/23/2015.  Tubes were all tested for shorts prior to GM testing; each tube was tested 3 times for review and to verify accuracy of testing.  
 
Tubes are NOS and have seen use, the amplifiers which they were used in are noted in the individual tube details. Some tubes include adapters and/or original packaging, notes are below.
 
NOTE:  Buyer is responsible for PayPal fee's and $8 flat shipping fee; even if multiple's are ordered, will combine the delivery.  Tubes will all be shipped via FedEx Ground and Insured for their sold amount.  If you wish for expedited, let me know so I can quote accordingly.
