[Hallicrafters] Dampp Chaser II

[Wayne Light]

Several of the guys on this list have written and asked about the responses I received regarding the use of this device in some of the Hallicrafters Radios (SX-101, etc.). I thought I would respond this way, since there may be others that didn't write and are interested.
 
The majority of the responses, from the experts, agreed that Hallicrafters put this resistor there to keep the oscillator section warm and therefore more stable...so when the radio was turned on, there would not be a significant change in temperature.  Only one thought it was actually used to keep the dampness out of the radio.  This little resistor is "in line" even when the radio is off and constantly gives off a little heat (of course, the radio must be plugged in :).
 
The one I have in my SX-101 seems to be working, so I have not tried to find a replacement.  Several people wanted to know if there was anyplace to buy a NOS for this unit.  If anyone knows of a replacement source, please let the group know.
 
Thanks again for all that responded!
 
Wayne
