Wave Meter, Class D, No.1 MkII,
ZA-14269
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
Wave Meter, Class D, No.1 MkII, ZA-14269 Powered from 6 volts this unit was used to pre-set a Wireless Set No.22 to a designated frequency with a degree of accuracy better than just using the tuning dial of the set itself. The Class D Wave Meter can be used to pre-set a transmitter or a receiver to a given frequency within the range of 1.9 M/cs to 8.0 M/Cs |
Wave Meter all set up and in use. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
Front view of Wave Meter with the headphones unplugged.
|
There are a complete set of spares within the Wave Meter. Only one valve and one vibrator pack are used, the other valve and vibrator (on the left of the chassis) being kept as spare. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
All packed up for carrying. |
This photo shows the HT power supply on the underside of the chassis. The power supply generates the high voltage by using a 6 volt non-synchronous vibrator to energise a transformer which steps up the voltage from 6 volts to 140 volts, a Selenium rectifier then converts the 140v AC to DC. The DC is then smoothed and filtered and used to power the single valve used in the Wave Meter. |
