[Hallicrafters] SX-111 Questions

[Waldo Magnuson]

Hi SX-111 owners,
     I recently got a SX-111 (s/n 1110-12 204020) which came with a 
manual (not original).  I have a couple of questions directed to you 
who might have a SX-111.
1) The manual shows C-69A,B,C on top of the chassis centered near the 
back - my 111 has a tube there (6BY6).  The C-69 on mine (an 
electroytic) is mounted under the chassis near the power transformer.  
The manual has 14 tubes - mine has 15 tubes.
2) The tube in question seems to be very microphonic - tapping the 
receiver anywhere and it rings but the 6BY6 seems to be the most 
microphonic.
3) The procedure for checking and adjusting the Notch Filter is not 
very explicit in the manual I have.
4) The crystal calibrator seems to stay on at times although I turn it 
off but this I need to check further before being certain.
Otherwise, when it's working properly, the receiver is very sensitivity 
and selective.  If any SX-111 owners have some thoughts on the above 
please share them.
    I am finding the path to CW operation is not a direct one - my code 
is almost there (well 90% at 5 wpm) and my General test samples close 
to averaging 90% so I guess I'm slowly getting there.
    Any finally, is the consensus to replace all black beauty caps 
regardless of how the set operates?
Thanks.
