Jorgen A-555 restored

Jorgen A-555
This is a compact Jorgen amplifier has been restored. All electrolytic capacitors replaced, new transformer installed. Also replaced small transistors with modern low noise transistors.
As usual, used audio grade Nichicon capacitors (Fine Gold, Gold Tune, Muse), low ESR Panasonic capacitors. Electrolytic capacitors in audio path upgrated to film Wima capacitors. All switches cleaned, cold solder joints re-soldered, idle current adjusted, max. power checked with oscilloscope.
During testing it surprised me with sound quality, this is good example of sound improvement: big difference before and after!
On moderate levels it sounds powerful, with plenty of bass and mid bass, very enjoyable.
It makes you think that it is high current powerful amplifier.
Another advantage is good signal to noise ratio, even with noisy sources like PC sound card.
Demo and pick up - Canning Vale.
