A working diary was maintained throughout the rebuild. This serves as a visual confirmation that something was done as opposed to using ones memory.

Such as "retightening ALL HV connections before turning power on. There were times during the rebuild where it was necessary to disconnect something in the HV circuit. I didn't want to forget to reconnect and tighten, so a deliberate note was made on the "Things to re..." page.
