I’m guilty of not spending very much time tweaking my home theater (and its starting to really show) — I’ve been working on building my new theater room, so all of my free time is construction at the moment.
I’ve also posted two new files, the 3300/4300 service manual and the 3600/4600 user manual. See the file section http://www.lowtek.ca/ampro/files. If anyone has other manuals to contribute I’m happy to host them.
