With the 15GP22 showing life and promise, I am now proceeding to the chassis.

It is filthy although relatively complete. The selenium rectifier shield is missing along with the back cover and four knobs. The cabinet is in surprisingly good shape apart from the speaker rust. (I plan to dismantle the original speaker and derust via electrolysis).

But the main concern is first to clean up the chassis and remove a fair bit of corrosion from the mouse home. It is pretty extensive in the corner next to the first Video IF but not irreparible.

I noticed that the front part of the chassis contains almost all the corrosion. I see that the corroded front section is attached to the rest of the chassis with self tapping screws. So I plan to begin carefully documenting and photographing the wiring crossing the chassis bridge and separate the chassis away to attend to the localized rust.

I have photographed the front chassis attached to the main chassis below.
