1970's JVC Amplifier Separate. (Biggar ML12)

I have this JVC amplifier that has just come available as I have bought another. It is in fair condition for a 46 year old amplifier with a minor dent on cover and minor scratches over decades of use. Fully functional apart from the AUX input of which one of the terminals are squawking (perhaps a dry solder joint?). It has 30W per channel and offers a lovely deep analogue sound of the era.
