Regardless of the branding (Amperex, Valvo, Siemens, Calvert etc) the Holland made 7119=E182CC (although not a direct substitue but similar to 12BH7 with a 10,000 heater) is a premium quality twin triode. An excellent substitute for the 7044, 5687 and 6900.
Perfect for the following equipment: Modwright preamp. Audio Note: DAC 4, Jinro amp, L3, M3. Various Manley units, Ray Samuels Raptor, B52. Aria VW5XL. Modwright Sony DVP999ES. Audion 845 Black Shadow. Bottlehed Smack.
Enter qty 2 for a matched pair. Various brandings, all are Holland made. $79.99 per tube
Very sweet sounding tubes with smoother low end and crisper high end than the original driver tubes. This is strongly recommended in tube-rolling threads, among others. Well worth the cost to upgrade.
