An excerpt from the studio maintenance log

The Sony / MCI JH-24 2" tape machine was not recording properly on track 9.  These are my notes detailing the troubleshooting process, and eventual solution.

Mixer repair

If only it was always this easy to find the point of failure. Note opamp cracked in two. When (and how!) the frig did that happen? Unfortunately that was not the only bit needing fixing today, and the others were not so easy.
