This Sansui 6060 was purchased by Ed and he wanted the unit restored. After the work I’m glad he did since the receiver sounds as great as it looks. First up was the amplifier board. New Panasonic capacitors, low leakage caps replaced with stacked film, and bipolar caps replaces with Nichicon ES. The two pairs of input differentials 2SA726 replaced with KSA992.

Next up was the power supply and protection circuit. New capacitors and replaced the Omron speaker protection relay with new.

The amplifier filter capacitors were replaced with new Panasonic THA series which fit perfectly into the original mounting holes on the PCB. Capacitance was increased slightly and stacked film bypass caps were installed under the chassis to help with low and high frequency response.

The phono preamp is locates under the chassis in the back left corner. Stacked film caps were used for the 1uf in the signal path and Elna Silmic II caps were used for the 3.3uf in the signal path. There was a pair of tantalum caps on this board which was also replaced with Panasonic FC electrolytic. There was a significant drop in the noise floor of the phono section after the work.

Lastly, the preamp is very difficult to gain access to. The front of the chassis needs to be unscrewed and the controls unfastened from the front panel. I found it possible to pull slightly down on the front panel and the board was able to be turned and lifted out. Signal path caps replaced with stacked film and Elna Silmic II again, and 2SC1333 transistors replaced with Fairchild KSC1845.

Here is a picture of the removed part carnage.

The dial and tuning meter lamps were replaced with warm white LEDs. As with most Sansui models it was best to reverse the bulbs in the dial and let the diffuser disperse the light into the dial. It looks original and sharp. The meters always come up bright in photos but have a nice warm sharp look as well.

  1. Mike,
    I got the Sansui here safe & sound. You’re packing protected it very well during shipping too.
    I am delighted with the way it looks & sounds. Happy I had you restore it for me too. Sourcing a piece of vintage Hi Fi gear is the first part of the equation, having it expertly brought back to factory specs is the other. What I have is a brand new Sansui 6060 that I’ll use and enjoy for the rest of my life.
    Best regards,
    Ed

    1. Thank you for your kind words Ed, and I am so glad to see the 6060 is going to be enjoyed for years and years to come.

      Cheers!

      Mike
