Yamamoto Sound Craft A-06-3 AD1/AD-1M Single Stereo Amplifier

This is a single stereo power amplifier that uses AD1M, a modern reproduction of the European-made vacuum tube AD1.output tubeIt uses a single two-stage amplification amplifier system that brings out the fullest appeal of the product, and the drive tube has a long life and a highly reliable C3m vacuum tube that achieves clear sound across the entire band. The power supply section uses a current regulator circuit, giving it a clean and energetic sound.

Single stereo power amplifier using AD1M, a modern reproduction of the European vacuum tube AD1.

Tripoleoutput tubeTo make the most of the characteristics of the circuit, a single configuration has a maximum output of 4W x 2. You can choose between Emission Lab and Telefunken's products, so you can make the most of your unique features.
The rectifier tube uses the same side contact type European vacuum tube AZ-4 as the AD1, and all vacuum tubes are made in Europe, creating a European sound. A self-biased circuit was adopted to ensure stable use of the valuable AD1/AD-1M vacuum tube, and the AD1 features were brought out by a no-feedback configuration.

output tubeIt is equipped with an ammeter that allows you to check the current at any time.
The capacitors are made of polypropylene film capacitors that react quickly and have little distortion, while all transformers use a high-performance original high-bee cut core transformer and Teflon insulating paper to achieve excellent sound with little distortion.output tubeBy inserting a timer relay into the grid, you can use it safely for a long time.
The company's original pin jack, which uses chrome copper as the input terminal, and pure copper as the speaker terminal. The speaker terminal is only an 8Ω output terminal, but there is no problem with using 4Ω and 16Ω speakers. However, in both cases, the maximum output will be lower. If the maximum output is 8W, the output will be around 4-6W.

The playback sound is based on the moderate range, mainly in the midrange, creating a neat and simple sound. The tone and sound quality are light and refreshing tone. The preview was mainly done by Emission Lab, but it was made by a vintage Telefunken company.output tubeThe sound quality is just right.

It's a Telehunken ball with a gentle and gentle tendency, and a crisp, refreshing emission lab ball, but you'll have to choose based on your preferences or the environment (equipment configuration). Although the overall performance is small, it is fun to listen to small pieces, focusing on the charm of the realistic reproducibility of the song's vocals. In general use, you can enjoy it without worrying about small output.
