Soundlumia's Opinion
The "textbook Heerlen sound" has been referenced in several Soundlumia listings of Amperex Holland E88CC/6922 tubes, and many tube enthusiasts asked what that all means. So this is the answer: the timeless Philips radio tone that many of us grew up listening to, the classic tonal template for all the great (and greater) Amperex Holland/Philips E88CC tubes, including this gorgeous Valvo-labeled pair. Valvo was the Philips Germany division.
Made in Heerlen, Holland in 1970, these tubes naturally share all the remarkable characteristics of the "textbook" Amperex Holland house sound. The midrange presentation is transparent, natural and expansive, with a slight touch of warmth that illuminates your music. Bass is deep and well controlled and the accuracy feels very similar to the high end German E88CC's. Sound separation and clarity on these are nearly on par with the Amperex PQ (Premium Quality) tubes - you should hear absolutely nothing but the pure soul of your music and all of it when you use these tubes.

Appearance & cosmetic condition
This pair is extra rare because of the excellent cosmetic condition: at least 90% of the inscription is intact and perfectly visible, and the acid etched Heerlen date codes are perfectly visible:
7L5 ⊿0I2 (7L5 = E88CC production #5, ⊿ = Heerlen, 0 = 1970, I = September, 2 = Week 2 of production month)
