Ferguson HiFi System 30 Stereo Tape Deck Tuner Amplifier. Basic Tests.

Very limited tests. All units power up, mechanics of tape deck seem fine & output on both channels. Haven't tested record. Tuner has signal. Amplifier seems to have very low output on both channels, one slightly higher than the other. I'm not entirely sure my leads are good, they're old DIN connector leads. Used, some marks, please see photos. No leads supplied. Please see photos for all connections. All will need mains plugs fitting.
