Fixin' BC-221-AK reference crystal oscillator drift down with increased
temperature.
After much advice I am inclined to test a different crystal. Please
rattle the junk box.
In need of a newer type DC-9 1000Khz crystal in Metal Tube Can, with
Octagonal tube base; The existing crystal has screws on the bottom with
a retaining plate and rubber gasket. I remember seeing some that were
completely sealed. This is key, need sealed unit no screws please.
Please contact off list. I need only 1. Will post a thanks to the list.
Thanks
Hutch
PS
For those who have been following my travels through the BC-221-AK
restoration. The 6pF capacitor is a Black Coated marked with 6 smuge
smuge mounted across the Crystal tube socket. After reading much on the
WW-Web I have come to the conclusion the capacitor is a 6pF ceramic NPO
type, though it was not indicated as such in any documentation I was
able to get my hands, eyes, on.
