Description
Victor JA-S22 Vintage Integrated Amplifier – Fully Serviced & Tested – Made in Japan
The Victor JA-S22 is a beautifully engineered vintage integrated amplifier from the late 1970s, featuring classic Japanese Hi-Fi construction, an elegant aluminum front panel, and distinctive logarithmic power meters.
This unit has been professionally serviced and fully tested, delivering warm, detailed analog sound while preserving the character that vintage audio enthusiasts appreciate.
Professional Service Performed
To restore reliable performance, the following maintenance has been completed:
Main volume potentiometer cleaned
Function selector switch cleaned
Speaker protection relay contacts cleaned
Preamplifier circuit repaired
Power amplifier circuit repaired
Darlington power transistor IC replaced
Idle current (bias) inspected and adjusted
These repairs significantly improved operational stability and reduced noise caused by aging components.
Fully Tested
All major functions have been tested and confirmed to operate correctly.
Phono input ✔
AUX input ✔
Tuner input ✔
Tape input/output ✔
Speaker outputs ✔
Power meters ✔
All switches and controls ✔
Measured output:
41W + 41W (8Ω, 1kHz, both channels driven)
Sound Quality
After servicing, the amplifier produces clean, dynamic sound with virtually no noticeable crackling or contact noise from the controls.
Because this is a vintage amplifier approximately 48 years old, there is a slight left/right output level difference at certain volume positions due to normal aging of the original volume potentiometer. This can easily be compensated using the balance control and does not affect normal listening enjoyment.
Cosmetic Condition
The amplifier is in excellent cosmetic condition for its age.
Clean front panel
No significant dents
Only minor signs of age
Please examine all photos carefully before purchasing.
Included
Only the items shown in the photos are included.
Important Notice
Although this amplifier has been professionally serviced and fully tested, it is a vintage electronic component that is approximately 48 years old.
It is therefore sold as-is with no long-term guarantee.
Please purchase only if you understand and appreciate vintage audio equipment.
The amplifier will be carefully packed and shipped securely from Japan.
