| EFC3/AD28.11.29 contd. -3- In the 20 HP. case tests so far indicate that whereas the cutting in and minor output can be suitable and as described for the Phantom case, the possible major output will not be large enough, and the ordinary higher output dynamo may have to be retained. We hope very shortly to be in a position to put intermediate output dynamos on experimental cars. EFC. | ||
