Many Tiger 2-XL tapes may be archived on a fansite
The website noted below claims to contain recordings for 43 out of 44 of the U.S releases of the Tiger 2-XL. I haven't looked through the whole website yet to verify, as we are talking about roughly 80 minutes per tape, which comes to 3440 minutes or 57.33 hours of audio. There appears to be no way to directly download the audio, and no contact information for the site owner.
This site was down for maintenance at the time I wrote the Tiger 2-XL article, and due to the way the audio player was implemented, there was no way to retrieve the audio via the Wayback machine. While the site is up, the only way that I know to retrieve the audio is to play it back in real-time on one PC and record it across to another PC. This will take time. I don't want to mess with the tables on this page until I (or someone else) has time to verify that the recordings are complete and can transfer them to to the Internet Archive. I don't want to see the website go down again and see these recordings vanish.
