Working arrangement but, in reality, LA-975 was designed mainly as the back two amplifier channels for a 4-channel system. Lots of stuff in the box and the back panel that aren't needed for a good quality 2 channel system. But obviously, it can work as an amplifier for a plain two channel system.
The Lafayette LT-725, 725A, and 725B tuners were good tuners. We sold a lot of them. If you're were lucky enough to get the original LT-725 tuner, that had a SCA button on it to receive those broadcasts. Some company (maybe RDS, don't really remember) threatened to take Lafayette to court for supplying equipment to receive SCA broadcasts. SCA was a "pay to listen" sub carrier broadcast. So, Lafayette removed the circuitry and references, and the LT-725A was born. You will notice on the LT-725 ad posted below, 2nd push button from the right labeled SCA, there is no mention of this feature or button in the ad text. Maybe, LT-725 marketing people knew they were threading on thin ice.
