Tektronix TM503 power module and plugins

I have one of these which is excess to my needs and I'm going to offer it with a DC503 counter, DM501 multimeter and either a PS-501-1 or a PS-503 power supply - whatever I have duplicates of.

This ensemble will give you the basis of a nice benchtop lab and the TM503 will accept up to three single-width modules or a double-width (such as an SC502 scope) plus a single-width unit. All three slots are populated with power connectors and it has a high-power compartment.

It any of you folks want the equipment let me know and I'll get some pictures up on the site. $185 plus shipping.
