Cap with cardboard is the one that goes. If it opens the
pix will pulsate, if it shorts will give a loud hum then
pop breaker. The cap is probably the same on all Zeniths
from abt E through K model sets. Milllions were built.
Cap in hoz out is the right one. That only applies to E & F
models anyhows.
Easy test is put a 4A slow blow in place of breaker & see
if it blows.
