YAMAHA CA-1000II Integrated Amplifier

Thank you for viewing.
This is a listing for a fully functional YAMAHA integrated amplifier, the CA-1000Ⅱ.
The CA-1000 II is an A/B class integrated amplifier released around 1976, a vintage amplifier renowned for its delicate sound quality.
Thorough maintenance has been performed, and it produces excellent sound even when listened to daily.
The power supply unit uses large electrolytic capacitors (18000μF x 2) from the Yamaha A1 specification, which has improved the sound quality.
All electrolytic capacitors in the ±50V power supply have been replaced to stabilize the power supply.
The final stage transistors in the power amplifier circuit have been replaced with new equivalents.
Other components in the circuit (EQ circuit, etc.) have had degraded parts replaced, and maintenance has been carried out with consideration for durability and sound quality. It is expected to last for a long time.
The playback sound is particularly enjoyable, especially when playing records with an MC cartridge, as the instrument reproduction is excellent. *I am using a DL-103 (0.3mV) myself.
The DC balance and idling during A/B class operation are stable without fluctuation.
Sound quality checks reveal no noise, crackling during operation, or switching noise, so you can use it with confidence.
This is a recommended unit for those who want to experience the sound of the highly acclaimed vintage amplifier, the Yamaha CA-1000Ⅱ from 1976.

(Operating Status)
- All input terminals and functions: ①PHONO1 (MC/MM), ②PHONO2 (MM), ③TUNER, ④AUX1.2, ⑤MIC are all in working order.
  *PHONO1 input impedance switching (MC/50KΩ/100KΩ) function is also working correctly.
- There is absolutely no switching noise from any of the function switches.
- There is absolutely no crackling from the main volume, balance volume, or tone control volume.
- A/B class switching is also normal with no switching noise. (The microswitch for A/B class switching has been replaced with a new one.)
- The headphone output is also normal with no contact issues.
- The power indicator lamp has been changed to an LED, so it will not burn out.
