Yes, you need a step down transformer. These are often rated in watts (the power rating is the same on both sides of a transformer) so it is easy enough to match this with the power consumption of the stereo. Apparently you will need about a 4kW transformer eg

There really isn't a lot to a power amp to be operated. This one differs from most in that it has an input level control and VU meters.

Dynamic 150 + 150 Watts Power Output, Generous High-power Design

The Spec-4 employs DC construction which excludes capacitors from the NFB circuits and uses a dual transistor differential amplifier with a current mirror circuit in the 1st stage. This provides a stable operation and also high gain over a wide frequency range. The pre-driver stage is a class A amplifier circuit with a regulated current circuit for the load. This makes for high-gain amplification with superior linearity. Furthermore, there is an overdrive limiter and power limiter circuit which is designed to protect the power transistors and make for added reliability.

The power stage employs a 3-stage Darlington pure complementary parallel SEPP circuit.

The SPEC-4 delivers**Continuous Power Output of 150 watts per channel, min. RMS, at 8 ohms from 20 Hertz to 20,000 Hertz with no more than 0.01% total harmonic distortion.**

**C****ompletely Independent and Perfectly Stable Left / Right Power Supplies**

The mighty power supplies are completely separated for the left and right channels. Also, each channel is provided with two 22,000uF large-capacity electrolytic capacitors and large transistors with a superior regulation. They achieve outstanding channel separation and a clear, powerful reproduced sound, in addition to the wide frequency response. There is a built-in surge killer circuit to suppress inrush currents from the power transformers and high currents which charge the electrolytic capacitors. This circuit ensures that none of the parts are affected by these adverse currents.

**
Protective Circuits Composed of Fast-response Relays and Electronic Circuits**

Each channel is protected by a DC and over current detection relay circuit. In the event of the speaker terminal shorting due to poor connections or when DC current is generated in the output, the output circuit is immediately disengaged and the speakers and transistors are safeguarded against any possible damage. The protective circuits also function as muting circuits when the power switch is turned on and off.

**
Peak Level Meters with Outstanding Waveform Response**

This power amplifier incorporates logarithmic compression peak meters with a wide scale (-40 -+3dB). With 8-ohm speakers, they allow the output to be read out from 0.01W to 300W. Moreover, the meters feature a fast response for peak signal indication. In addition to the peak output reading, it is easy to interpret the dynamic margin with respect to the SPEC-4’s clipping level.

**Input Level Controls with dB Calibration**

The SPEC-4 is equipped with input level controls with direct readout attenuation values (-dB). These can be used to continuously adjust the input levels for each channel in accordance with the rated output voltage of the preamplifier. In this way, the SPEC-4 can perform the proper gain control according to the preamplifier’s output level. The preamplifier will thus be used in the condition possible for the best S-N ratio and distortion characteristics.

**Stylishly Professional Front Panel Design**

Just as you would expect from a sophisticated system, the SPEC-4’s front panel is professionally designed with the large level meters in the center. Also. The front panel’s dimensions allow the model to be mounted in an EIA standard rack, just like real professional-use amplifiers.

400 watts delivered to 300 watt speakers the only way to do this would be to wire two subwoofers in series so that the power needed to drive them will be 600 watts to max, however this will increase your impedance on the speaker (8 ohms) load so what you can do to compensate is get an 8 ohm 600 watt resistor and put it in parallel with the speakers you will then have 4 ohms of impedance at a total capacity of 600 watts of power
In other words the amplifier won't blow these out now.

I need the output voltage values of the power transformer to fix it. The source voltage is 220 volts - 50 Hz. Please, send me the output voltage values of the power transformer to help me fix my Inter-M amplifier model M-2000.
