This pair is now sold. PM me if you desire to-tier 6DJ8/E88CC/E188CC types. Siemens ECC88 - 6DJ8 - 1961 date codes on both - test very strong with balanced triodes on my Hickock TV10-Du tester. CONUSA sales only. Price is $125 shipped to your door - all inclusive. Thanks for looking.
PS. Whereas it is very rare for me to have ECC88, I liked the way these in particular sound - quite different than the Hollanders, TME. These from Munich Germany are much rarer than the Philips/Amperex versions.
Forgive earlier typo where I listed this as E88CC - was totally a rushed senior moment. Thanks Ceylon for pointing out my error.
