I have a nice pair of GE 5 Star 5751 triple mica blackplate tubes for sale.
These are commonly used as 12AX7 substitutes even though their relative output is 75 rather than 100.
These are high quality mil-spec tubes with 3 micas, blackplates, and support rods.
This pair has good to very good logos with 57-20 and 57-30 date codes.
They tested 95/95 and 95/95 on my Sencore tester where 70 is the minimum good reading.
Asking price is $75 including PayPal fees and USPS 1st class postage to USA.
I also have a 3rd tube with same build but virtually no logo available at a slightly lower price if you are interested.
Pictures coming soon.
Feel free to ask questions.
Thanks for looking.
