Transplanting the power supply (the UCC-6) from one Teletype model ASR 33 to another (or from a KSR-33) is much easier than I thought it would be. I thought that there would be a lot of complex re-wiring, desoldering, and re-soldering. Not so! Here are the simple steps.
The entire UCC-6 will easily pull out. Install the replacement unit and re-attach the screws, ground, and molex plugs. NOTE: If the computer interface was attached to the terminal strip, you'll need to re-attach that, too.
