I thoroughly enjoyed David B.’s post on magnetic tape and Dave M.’s comments on carts. Thought you might like a few pictures of the “evolution” of the tape machines we used.
First, is the machine a lot of us cut our teeth on, the Magnacorder PT-6. My first station (KCLA) actually used these not only for recording, but also for playback of commercials and promos on the air, which was a challenge as the machines took about 2 1/2 turns of the reels to come up to speed, making it necessary to hit the switch for the spot several seconds before you wanted the audio to start.
Next is the workhorse of KAAY, the Ampex 351. The transport controls on these used some pretty large relays, which meant they made a rather satisfying “ca-chunk” sound when you hit Play. Incredible machines, as evidenced by the fact that they were introduced in around 1950 and still in use at KAAY and a lot of other stations in the late 70’s and even into the 80’s.
Finally, the Ampex AG-440. Starting in the early 70’s, this is what we considered to be the Rolls Royce of tape machines. There’s a lot of fond memories of material David B. and I produced on one of these in the old KLAZ production room.
Hope you enjoy.
