As implied by its name, the Baby Amplifier is quite small, 18cm wide, 23cm deep,
and 13cm high (7in x 9in x 5in), and weighs about 7kg (15 lbs). The Baby Amp is
rated at 10 watts per channel with distortion listed as less than 1% at full
rated power. More important than distortion ratings, the frequency response of
the Baby Amplifier to be an astounding 6Hz to 80KHz at ±3dB (12Hz to 45KHz at
±0 dB) and a signal to noise ratio of -95dB. These specifications are achieved
using a Class A, push-pull circuit with output tubes wired in pentode mode and
using minimal, global negative feedback. Solid state diodes take care of power
rectification. Nominal speaker impedance should be 8 ohms.

The 4 tubes are Russian military 6P1T pentodes, treated by Sophia for low
noise. While the 6P1T is similar in dimensions and outward appearance to the
EL84 family of tubes, they are not interchangeable due to significant
electrical differences. A visual comparison with an EL84 reveals that the 6P1T
has substantially more robust construction. The input/phase splitter tubes are
American-made, NOS 5670, medium mu, 9-pin miniature dual triodes.

Sophia Electric has designed the Baby Amplifier to be as inexpensive to produce as
possible, while maintaining the fine sound quality of their more expensive
amplifiers. To this end, the chassis and printed circuit board have been
outsourced, but voicing and final assembly of the amplifiers is done by Sophia
Electric. The tube sockets, which are mounted on the PC board, are located just
below the top surface of the amplifier chassis. Unlike some PC board mounted
tube sockets, the Baby Amp's sockets have a solid feel when installing or
removing tubes. The transformers are located beneath a slotted metal cover at
the back of the chassis.

The back panel contains the RCA input pair, the IEC power connector, and four UPGRADED speaker binding posts. This is a fantastic little amp, check out the
reviews and decide for yourself.
