    I thought I had it figured out but I thought wrong...maybe.

    Is it the same as most of the Yamaha theater amps or a different animal?

    Most likely. AM/FM reception hasn't changed much.

    The better the external antenna the better the reception.

    If you're talking about connectors, I think (not sure) some of the newer Yamahas have DIN antenna connectors and the T-85 likely acepts 300-ohm twin-lead and/or 75ohm coax connectors. But your post leaves out a lot. What are you trying to figure out?

    The T-85 has one of those old school slide on DIN type RF connectors for FM. I drilled a hole beside it and added a "F" type connector. I just soldered a short piece of coax to the existing connector metal bits that run onto the pcb. It works fine.
    There is no 300 ohm balanced in this design.
    I have a RX-900U receiver as well, same crappy FM connector.
    The AM antenna looks like it is common to many other Yamaha units. My T-85 did not come with the AM loop antenna. I would have to check the service manuals to confirm what models used the same AM loop.

    Technically it is called a PAL or Belling-Lee type connector.

    Simple adapters are available to make it compatible with F-59 type connectors.

    I have a box of them somewhere.

    I have tried above since it is the easiest to obtain. the problem is that the center pins is a smaller diameter (designed for a "F") than the PAL or Belling-Lee type connector center pin socket, so it is not a very good fit but is better than nothing.
