    Looking for a little help from the HiFi guys on the site

    Got the bug to build a vintage hifi system and picked up a Sony 1120F integrated receiver. Fuse cap was missing - never a good sign but it followed me home anyway.

    The power supply is missing two pigtail fuses and has a burnt trace that once connected to the power transformer.

    I have a feeling that a few more shoes are going to drop on this one so I'm scouting for a service manual.

    I've downloaded the TA-1120, 1120A and 1130 manuals thinking they might be close, but the circuits are quite different than the 1120F.

    Any help here would be greatly appreciated.

    Get power supply up and running first.

    Yes - Solid State, powered it up on a limiter, indicator lamp lit on front panel, discovered missing pigtail fuses (6.3V) on power supply board.
