[Boatanchors] Dampp Chaser

[Harry Vaught, KT4AE]

 From aging, but recent memory, the Dampp Chaser in my SX-101A is a 
metal enclosed unit clamped or riveted to the chassis - not just a stock 
resistor.  Aren't some resistors built that way to use the chassis as a 
heat sink?  Does my Ranger have one?

They may have found that any old hot resistor would do the job.

Mine used to be not much better than an SX-100, stability-wise, but 
after replacing the 12BY7 yet again, it has really locked down.  After 
it's been on for a few minutes it's really stable.

I used to wonder what good the "Dampp Chaser" and always-on filament in 
the 12BY7 did (other than using up 12BY's), but now I'm a believer.  It 
actually didn't settle down until it had been plugged in for a couple of 
days after the last osc. tube.
