Yesterday night I mustered up all my courage and attacked the capacitor can.
The 16's can is the most hated type (by me), same as the 20's one. It is narrow and deep, and this makes for very inconvenient extraction.
I separated the cardboard from the tin as much as I could, by squeezing the sides and running a flat thin screwdriver between them, and tried to shake the contents out. To my surprise I saw the movement, which was a good sign.
Then I put a corkscrew with wooden handle in; this somewhat expanded the contents, but then I used the thick metal vertical piece that bolts the can to the side of the chassis as the lever against the corkscrew handle, using large vice as the fulcrum, while heating the can with the Milwaukee gun. This pulled the contents about 1/2", then the caps inside separated and I was able to extract the whole thing without much mess at all.
Got lucky.
I had the plate with the new caps already assembled, put it together, soldered the ground wire to the can, and voila! - the can was done in 1/2 hr (yes, took me about that much to figure out what to do).
One small step for this radio, and a huge relief for me

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
