Kenwood TM-741 Repairs

 This is a Kenwood TM-741 tri-band mobile. These were way ahead of their time, when they came out in 1992. It was connected to an antenna when a near lightning strike made it deaf on 220. The owner put it on the shelf for many years, then it came to me for repairs. During it's downtime, the memory battery failed and several caps started leaking. I replaced the battery, recapped the motherboard and all 3 band modules, replaced a FET in the 220 module, repaired oxidized connectors on the band modules, and got it back on the air. Here's a couple of vids and pics...
