    i was going to ask for help, my FM and Phono work on both channels but the AUX is good an one side and just line signal on the other.
    When I jiggle the RCA jacks it comes back....I feel so smart.

    Now I just have to figure out how to access the back of the inputs to re-secure the unsecured.

    Needs faceplate glass and some lights, should be a fun project.

    With headphones it's all good. I've got problems downstream.

    Very nice receiver you have there, l have wanted one for a fair while. Yes should be a fun project, as you say looks like time for new filter caps.

    No BOM for the 881? How does one make a BOM? The variables are daunting.

    I know you will love it. I have one and its a often overlooked model. I think for at least for my ears its one of the best sounding Sansuis I have had or currently have. I sadly am pretty naive as to how to fix all but the simplest issues. I did just change out my dial lamps as I had one out but other than cleanings and the obvious in my face issues I am afraid I have a friend whom is a guru. I did bring mine out for some play in the last week and its been singing ever since.
    Please keep me posted as to your progress!

    If you can't find a parts list here just go through the unit and make up your own list, (also some of the values in the service manual may be incorrect). This is what l normally do and it doesn't take long at all. When you have your list then you can use whatever capacitors/transistors etc you feel most comfortable with.

    This thread may be useful.

    One of these big filters is toast. Guess which one...

    It vented. All over the by-pass resistor. Note the splatters on the chassis.

    I would go with MOX to replace those carbon composite resistors.The lead is probably corroded on that RH one.. Metal oxide mox.

    Near perfect, I figured if the outside looks good. any malevolence that lurks inside can be fixed.

    But I'm here because of the priceless advice I get for the cost of a subscription. As it's just a bleed off I figured a resistor was a resistor.

    Thank you.

    BTW, USAF 462 (loader) 1982-1986. I LOVED my 2+ years on Okinawa.
