You may have bad cap/s around the horizontal output,
especially the high voltage one at the HOT's collector.
(.015 X 1.6kv or similar)
As for the HOTs you have a wide choice, if you want
to use the original, and have only one just keep it.
2SD1885/86/87 will be perfectly adequate. Even
2SD1880/81 will work fine despite the original being
a damper-less 1885. So you can blow some more
with confidence (I would leave yoke connected
if I were you)
