Vintage TECHNICS SU-50A solid state integrated amplifier junk For Repair

  

An integrated amplifier released by Technics in 1969. Technics, which achieved OTL (output transformer-less) with the 5-parallel push-pull tube power amplifier SU-20A, has achieved Japan's first OCL (output capacitor-less) with this SU-50A, After that, OCL became popular as an amplifier circuit. I was able to get sound, but there are many problems. There are times when the speaker selector does not switch.

The input selector switch is hard. There is a poor contact on the knob. This is a junk item. We do not mark merchandise values below value or mark items as "gifts".
