Tektronix 1503B

Workshop Project #36 - Tektronix 1503B TDR This one took quite a while to complete. Why would I need one of these? Well, getting into some radio stuff more and more recently, I thought it might be good to make sure any antenna cable is halfway decent at least. This unit seems to be still in use by several hobbyists at least, and there's quite a bit of modding info out there. The LCD display is a known failure point, especially the EL backlight. In this video, I do the usual cleanup and repair of the device, so that it does provide proper measurements again. 0:00 Intro 1:33 Getting into the case! 4:10 First peek to PCBs / Main PCB Removal 5:26 Power Supply Removal 6:50 Analog PCB Reveal / Front Panel Disassembly 8:25 Recapping! 10:15 Display PCB Cleanup: Disassembly and Column Board 12:34 Row Board and Assembly 13:40 Battery Pack Disassembly 15:22 Battery Welding and Assembly 17:05 Line Filter / Power Supply 18:39 Case Lid 20:56 System Test... / Chassis Rebuild 22:45 Printer Overview and Disassembly 25:07 Pinch Roller Rebuild... 29:25 Printer Assembly: Feed Unit and Front Panel 31:58 Printer PCB / Print and Feed Unit Mounting 32:50 Springs...
