Wireless Set No. 52 Canadian - Project

[David Dunlop]

Good Evening, Mike.

Don’t let the 52-Set Receiver fool you. It, along with its related Crystal Calibrator and the two Vibrator Supplies used to power it (the ZE-11/12 Remote and the Vibrator Section of the Main Supply Unit) are definitely the low voltage demand parts of the 52-Set. Those little ¼-watt resisters work very well there.

There are a total of 130 resisters used throughout the 52-Set. Of those, 66 are ¼-watt rated, and of them, 49 show up in the receiver circuits. The rest are in the Sender.

Next step up is the ½-watt rated resisters, and at that point a dramatic shift is already taking place. There are 31 ½-watt rated resisters in the entire 52-Set. At this point though, only 8 are in the receiver circuits and the other 23 are in the Sender.

The balance of the resisters fall between 1 and 50 watts rating and with a handful of exceptions all are found in the Sender and its related twin dynamotor supply. With those components you are in the realm of 1,000 to 10,000 volts to control.

Best regards,

David
