This HRO is Blue
An original paint job.
All the others I have
seen are Black.

The receiver uses a separate mains
power supply capable of supplying 240 volts DC at 70 milliamperes and 6.2
volts AC at 3.4 amperes, although lower plate voltages down to 135
volts may be used with some sacrifice in performance.
A separate
loudspeaker is required.
The band change is by plug in units, which are
housed in a separate wooden box as pictured when not in use.
The HRO is a
very stable receiver and hence was used extensively at listening stations
though out WW2 and for some time later.
The weight of the HRO Receiver including
the 9 coil sets is 51 lbs - 23.1kg. |
