[Hallicrafters] HT-33A Fan Assembly Needed

[Paul Kraemer]

Gary
Kudos on the very nice find!
WW Grainger has a nice selection of these shaded pole fan motors and high 
efficiency blades commonly used in small exhaust fans and range hoods. The 
old mounting centers were typically 2" which is now 1 7/8", other than that 
they are very close fit. I found one for an SB-200 linear. Motor plus blade 
were about $17. At the time I noticed that the same one also fit a Heathkit 
Warrior and CE 100V
The 3.5" computer fans run off a couple diodes on the filament transformer 
do a nice job too but many of them don't like being that close to rf.
