Audio-Technica AT-MA50 Stereo Mixing Amplifier
This is the Audio-Technica stereo mixing amplifier, model AT-MA50.
Regarding its condition, the right channel sounds clear, but there is no sound from the left channel. Therefore, when set to BTL mode (monaural), no sound comes out at all. The volume control operates smoothly without crackling, and the headphone and AUX terminals were confirmed to be in working order.
The left channel output is defective. Since there is no sound in BTL mode either, it is presumed that the power IC (STK4833) is faulty. This unit is sold as-is (junk) for parts, such as the power transformer, chassis, and right channel components, or for repair with the assumption of IC replacement.
The item will be lightly cleaned and carefully packaged for shipping.
