Schematic?

I can give you the data sheet: https://www.onsemi.com/pdf/datasheet/tip3055-d.pdf

Perhaps you mean a schematic for an amplifier that uses these parts?

I believe you were interested in subwoofer amplifiers: https://www.elcircuit.com/2015/12/ocl-subwoofer-amplifier-tip3055-tip2955.html

is that any simpler than that?

You can find a lot of schematics using their TO-3 counterpart 2N3055 and 2N2955. Yours are just a bit less power. Do you already have the power supply and chassis with heatsinks for the amplifier-to-be?
