Maximum Output: 20dBm @ 1.5% THD into 600ohm load
Badge Lamp: LED illumination
RF Remove Control: commands volume control UP/DOWN; uses 9V battery
Power Consumption: 55 Watts (485mA @ 120VAC)
Operating Mains Voltage: Units are purpose built for original destination country’s mains voltage: 100V, 120V, or 220-240VAC as indicated on the serial number badge. Power transformer must be replaced in order to change mains operating voltage. 120VAC units may NOT be rewired to put the primaries of the power transformer in series for 220-240V operation or a large radiated field of hum will develop. If changing locations/voltages, the power transformer must be replaced with the dedicated one for the voltage at which it will operate.
Mains Voltage Frequency: 50 ~ 60Hz
Dimensions: W=19”, L=11”, H=3 1/2”
Shipping Weight: 15 Lbs
6moons review here. "Because the Jumbo Shrimp does everything right, it will prove itself with transistor and tube electronics."
Features:
Very short, simple minimalist signal path. All-tube design. 2 x 12AT7 input, 2 x 5670 driver, and 2 x 7044 output.
Signal path furnishes very high dynamic range with prodigious input and output signal headroom.
Signal 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 motorised 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!
Dedicated 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.
Also can safely packing and shipping around Australia by buyer cost.
