Unusual Scott 340A Request

I am not sure if anyone can help on this. But, I have a Scott 340A I'd like to restore. I live close to a nice BIG water tower and since the town won't let me take it down(ha,ha). i would like to monitor the Multipath Product by adding a Scope to the Receiver. I have found NO help on doing this with this receiver by way of the Internet! I can build a circuit, but do Not know if this is possible, what i would need by way of an interface circuit and WHERE to wire in this unit. NO, since my money tree just has green leaves, I can not buy a McIntosh receiver! I can download the receiver's Any help would be greatly appreciated.
