Hitachi HA-270 amplifier restoration (part 1)

This amplifier was brought to the workshop as "working", but with a bit of intermittent issues in the controls. Upon checking the amp, I found quite some serious issues in the power supply section and I decided to do a full service on this one. It needs it urgently!
