Preamp tubes can subtly shape or change tone, gain and effect signal-to-noise ratios.

In Vintage H.H. Scott products, these Twin Triodes are typically used across the entire product range (Preamps, Integrated Amps, Tuners, and Receivers). Scott typically private-labled (OEM'ed) Telefunkens.

Typical applications are: phono input sections, Dynaural Noise Suppression applications, and tone (treble & bass) controls, and tuner AF line-level output drivers.
