Pure Class A analog preamplifier designed using high quality components.

The PAM-3 preamplifier is based on a state-of-the-art Korg Nutube triode valve with very low power consumption and high performance.

The input circuitry that drives the Korg Nutube valve is made up of manually matched JFET transistors. Like the PAM-2, it features an ALPS motorized potentiometer with remote control, a power supply with high-stability LDO voltage regulators, and high-quality filtering capacitors. Relays with very low contact resistance to avoid degrading the audio signal.
