AIWA HS-PX303 PX30 PX900 walkman - cassette player repair fix

In this video i have successfully repaired this king of aiwas - Aiwa HS-PX303 very nice walkman.
As you will see, this one was quite challenging one...
And there is one more thing - i have noticed some sound distortions for like 2-4 seconds after “cold start” isue was volume quick charge circuit and again bad transitor q11 - be aware if you have something the same check that transistor since it is in range of electrolyte spill.

As for all my repairs i use only Panasonic, Nichicon or Nippon Chemi-Con capacitors.
