Appearance & Cosmetic condition
This pair stands out aesthetically among the vintage tubes. At least 90% of the silkscreen is well preserved and the acid-etched Heerlen date codes are perfectly visible on both tubes:
I65 ⊿2D1 (I65 = ECC83 short plates production gen #5, 𝛥 = Heerlen, Holland, 2 = 1962, D = April, 1 = Week 1 of production month)
I65 ⊿2C3 (I65 = ECC83 short plates production gen #5, 𝛥 = Heerlen, Holland, 2 = 1962, C = March, 3 = Week 3 of production month)
Packaging
This pair of tubes will be packaged in new white boxes.
