SW1X PRE V Line Pre-Amplifier

PRE V Line Pre-Amplifier

Top-of-the-line DHT Pre-Amplifier

The PRE V is a signal output transformer (OPT) de-coupled 45 DHT tube output stage based, zero negative feedback (zero NFB global or local), line pre-amplifier design. The DHT tube output stage is similar to the output stage as found in our DAC V.
