Here is something NEW
SAF all A.C. ADAPTER
offers an economical way of equipping theatres for all A.C. Sound-on-Film operation. It is not necessary to discard the present amplification system.
The SAF ALL A.C. ADAPTER protects the theatre owner's investment in his present amplification system. It eliminates all batteries, chargers, generators, etc. It gives enough volume for the theatres up to 1000 seating capacity.
The SAF ALL A.C. ADAPTER fills a long felt want in the talking equipment field. The improvement is startling — for its elimination of hum — its sweetness of tone — its adaptability to all theatre amplifiers. Just think of it — by plugging into the output stage of any theatre amplifier, you convert the present equipment into the latest ALL A.C. set. With a built-in tone control, you get fidelity of tone and a frequency response up to 10,000 cycles.
The SAF ALL A.C. ADAPTER can be attached to all amplifiers used either on disc or film equipment. And it is not necessary to match impedances. Why? It plugs into a tube socket. Simply remove the tube preceding the output stage of the theatre amplifier. And insert the ADAPTER plug into the tube socket. See illustration.
The SAF ALL A.C. ADAPTER is a three stage high gain amplifier. It is designed to work into the power output stage of any make amplifier. It also contains the necessary controls for volume and voltage. And it supplies exciter lamp and photo cell current.
