Motorola 220MHZ repeater

[WB8JBG]

I have a Motorola 220 Mhz repeater with 5 wacom tunable duplexers. It has a large power supply in the bottom and a 400 watt amplifier with an antenna tuner built into the amp.. I tried to find something on the web but to no avail. Any info would be helpful. It is in working condition and I have pic's
