All-tube design. 2 x 12AT7 input, 2 x 5670 driver, and 2 x 7044 output.\u003c\/p\u003e\n\u003cp\u003eSignal path furnishes very high dynamic range with prodigious input and output signal headroom.\u003c\/p\u003e\n\u003cp\u003eSignal path also delivers high bandwidth, low noise, modest local negative feedback and low distortion, and is voiced for best musical performance. Radio-Frequency based remote command of the silicon-free high-quality motorized VOLUME attenuator set, for infinitely resolvable control of listening levels. No need to \"point\" the remote in any direction. Now the Shrimp's attenuator set can be controlled from another nearby room, through walls, floors and doors, and through opaque equipment closet or cabinet doors too!\u003c\/p\u003e\n\u003cp\u003eDedicated White Follower stage using the 5670 dual triodes effortlessly drives all passive interstage circuits; volume, balance and output stages receive crisp instruction from the Follower regardless of control settings. Generous energy storage via large power supply capacitors for more impact in the bass. No global feedback makes the Shrimp very fast sounding.\u003c\/p\u003e\n\u003cp\u003eNon-inverting two-triode gain stage is direct-coupled for most pure signal path. Cool White-follower output stage provides low 50 Ohm output impedance. This is much better than a boring plain ol' cathode follower. The Shrimp can drive anything, not to worry. Filament supply floated 80V above chassis ground for quieter operation and longer tube life. ALPS audiophile-grade balance and motorized VOLUME pots. We use the nice parts in here! MIT\/MultiCap polypropylene audiophile-grade signal coupling capacitors, including two 30 uF monsters on the output stages.\u003c\/p\u003e\n\u003cp\u003eWarm-up delay \/ MUTE button.
