Quote from a popular online tube retailer:

"A nice USA 1950s tube that was widely used in organs and hi-fi units. This is the original 1950s RCA black plate that will never be duplicated. This is probably the last time they will be offered at this price. Good supply now, but when they are gone..... Warm blackplate sound with a nice top end. MATCHED PAIRS ARE JUST $50.00."

I have a nice pair of 1960 Wurlitzer by RCA 12AU7A triple mica blackplates tubes with nice logos for sale.  One has clear 60-13 date.  The other has no date visible.

Tubes tested 88/89 and 89/88 on my Sencore tester where 70 is the minimum good score.

Asking $30 for the pair with no PayPal fee and $3 for USPS 1st Class shipping to USA.

See my other listings.  I will combine shipping and possibly discount prices if you purchase multiple items at the same time.

Feel free to ask questions.

Thanks for looking.
