[QuadList] Fans in a TR-5 and how may TR-5s out there!?

[Dale Lamm]

there seem to  be  two fan things inside the  cast  and one is called a compressor blower  but  it is a  fan  thingsu

[end]

The blower under the half-inch baseplate feeds filtered air into the headwheel motor for cooling. If your head takes high pressure air for the air-bearing (unlikely, you thought it was a ball bearing head), the connection is a nipple on the lower rear of the machine. Noisy compressors were kept away from the operators. There might be a small vacuum pump in the lower deck for the tape guide, or someone could have adapted a venturi system and removed the rotating vacuum pump.
