I have 5 vintage(1959/1960) 5751 tubes made in the USA by General Electric.The 5751 is part of the 12AX7 family and of course is interchangeable.Made for the US military its' characteristics are lower gain which equates to lower noise and less microphonics.Evenly balanced and nicely flat in their response they are appropriate for pre amp application.
All tubes have been tested and yield results in the 98/98 to 100/100 range.No gas leakage,discoloration or other defects noted.
3 of the original 8 have been sold so I am offering the remaining 5 for $50 shipping included.Shipping by USPS within 24 hours of payment.
