Remove whatever panels (back/bottom etc.) and take a peek. There should be some stamps or labels on the inside. You can't get parts unless you know what you have.
If you do find such a stamp or label, that's how you would get a service manual/schematic that will show all the parts for the amplifier. If you need a new needle, you must remove the cartridge to get the number off of it, to find a suitable replacement.
Don't treat it as a Trimline 500. Go according to the innards and work from the inside out, unless you are fortunate to find a user's/repair manual all-in-one labeled Trimline 500, if it does exist.
Like the Maggie folks here, you can't get a manual for a model 1-RP654. The same cabinet could have been used for several years, but the tuner/amp/turntable could be different/upgraded.
I don't know a thing about your particular unit, but in this case, possibly "think inside the box." --BB
