[Heathkit] SB200 Fan motor dumb question

[Mike Sanders]

Greetings and thanks to all who responded. I used a light general purpose
household oil
similar to 3N1 oil and managed to get the end bearings covered it appears.
The fan was probably
OK but not being sure I was looking for a clue as to frequency of oiling it.
Looks like every
10 or 20 years does the job :>). Wonder if Heath expected the SB200 to be
running 30
years later with same fan, same tubes and same power supply components? Bet
not.
I have the SB401 on the bench now and am currently scratching my head as I
look through
the manual. I Am getting anxious to get this set up on the air soon.   HNY
