Info on University Sound Receiver

I just acquired a Univerity Sound Studio Pro 120 receiver, made in the USA, and it indicates that it's made by LTV, which I think was the parent company of Altec - it looks to me to be an early 70's receiver, very simple layout, and has dark brown plastic toggle switches for all the functions. It appears to be about a 20 watt per channel receiver and falrly small in size, kind of like a Marantz 26 if you're familiar with that. Just wondering if anyone had any more info. Thanks
