The collector becomes a rectifier dynamo collector

The dynamo's collector
(photo at right) had to be

replaced with a part that

showed less, or no wear.
The dynamo's collector, along

with the carbon brushes, is re-

ing current (see edition 26).

The collector is a mechanical recti-

as early as the 1950s. But the di-

tubes (photo right) at that time
were still too big, consumed too

much energy and got very hot,
