As much as I like Motorola products, I always considered the set as a "Rat's Nest". Wires running all over the place. I worked on a few, but they only needed repair when several years old.
There was a problem with the monopole antenna breaking out of the mounting place, because of the strong spring used and careless handling. IIRC, Motorola parts made a kit that could be used to replace the antenna, without having to replace the entire cabinet front.
I had a larger 15" Cadet for a few years. That model used a voltage doubler power supply and one more stage of IF, a great DXer.
Of course, they antenna was broken out.
