That's what holds the xtal-filter 'rock' in a BC-312/342.  We had
a DC-8 discussion recently so this counts.  This isn't an octal-
socket fella, it's a screw-tab package that looks like a xmt mica cap.

My '312 had no xtal-filter action so I removed same.  Looks like horrible
job but, upon removal of a IF can, quite easy.

Tried dang thing in a CMOS 4011 test osc. / 100kc calibrator.  Ran
at 745kcs.

Dissambled, cleaned, & re-tested.  Again 745kcs.  Began loosening two 
'clamp screws' & thing changed modes to 470kcs.  Where it shud be.

Screws real loose & I'm hesitant to re-assemble.

Think rock 'X-Y cut' & 470 is mode down long axis & 745 up short one.  
But my last name ain't Bliley or Knights.

Any shared experiences?

  Thanks,

     Marty
