    Thanks for the table. Downloaded for as important reference information.

    The amplifier gain for the High output will be exactly 4, for the L output exactly 2.

    I measured the highest possible level at the High output. It turned out +12.5 dB on a load of 100 ohms.

    I tested with an external generator whose THD is unknown to me. Therefore, the maximum voltage was determined by the absence of visual distortion of the sinusoid shape.

    I assume that at this level, THD will be more than 1%, but less than 3%.

    Of course, such a high level will not be used in real life, but the power reserve will not hurt, especially on dynamic musical compositions.

    A sample of the "Bachelor" amplifier changed to 230 volts to 115 volts, got a face and is preparing to travel to the United States.

    The preliminary order form for the "Bachelor" amplifier can now be completed online. I present a screenshot. If you need to add or change fields, please let us know.

    No, don't. I will use the old list.
