Help with Phono - RCA Victor 18t AM Radio

[rodmonster]

Ok - update.
I did two things.
1. I cleaned out the RCA jack a bit in the back.
2. I found an OLD RCA jack from the 60s... momo analog... and sure enough - that worked.
I did need to use the tone dial - and the radio did keep coming through - until I got the RCA cable in to work - then it over road the radio.

Thanks for the help yall!
