Wireless Set (Canadian) No.19 Mk III Supply Unit No.2.

It provided 260 volt and 550 volt HT from an internal dynamotor. It could also supply the receiver 260 volt HT from a vibrator power supply that had a much lower current consumption. On keying the transmitter, an internal relay started the dynamotor and switched over the supplies from the vibrator supply.
