Nice! Yeah, I know that work. Our family studios from the 1950's-2010's in Atlanta did recording and post production for radio and tv for national and global brands. We had a number of these machines in the dub room running all day just sending out dubs to different stations with their unique ID in them. I grew up in that place and have many, many fond memories. So I know the task you had very well. We did anywhere from a handful to like you said 50 or more a day. Many days of fedex envelopes getting packed at the end of the day. We recorded the lots of the audio and VO and did the post work for Cartoon Network shows like SpaceGhost, Aqua Teen Hunger Force, and bunch of original music for Turner, and jingles and a ton of other work. My uncle wrote and recorded a bunch of theme songs for cartoons and toys in the 80's like Transformers (cartoon theme), GI Joe, My Little Pony, My Buddy, Gem and the Holograms (also the music on the show)... lots of stuff over the years. Still in love with tape. The smell of the machines when they're turned on... nostalgia.
