| PHILIPS LAMPS LIMITED. CONTINUATION. 2. Rolls-Royce Ltd. 13th April 1935. We can, of course, understand your objection to a special lead being taken direct from the battery to supply the set but, on the other hand, our own view with which you will probable concur, is that this objection is far less serious than the alternative of having to fit resistive suppressors in series with the ignition system. Yours faithfully, PHILIPS LAMPS LIMITED: A S Calkin Radio Technical Dept. Form No. G.8/135-50M-R.{Sir Henry Royce} | ||
