The Tektronix TM504 is a four-bay mainframe for the TM500 system. The rightmost compartment can supply a high-powered plug-in.

The TM504A is functionally identical, with the addition of a fan in the rear panel, and relocation of the power switch to the centre underside of the front panel. It was exclusively supplied as part of the F7523A1 MOD WQ Test Set, part number TS-4353-U, containing modules SG505 Mod WQ, SG505 Mod WR and AA501A Mod WQ.
