[Hammarlund] HQ-180 can capacitor

[Robert Sauvan]

Hi all,
I had been working on my HQ-180 replacing this and that and doing a 
complete alignment. It works fine (better than ever) but I still feel I 
have distorted cw signals somewhat. I had posted this previously and 
most pointed to the AVC section of the circuits but I have not located 
anything amiss there.  I am curious to know whether or not the 
possibility of one of the caps in my can capacitor might be causing the 
issue. I always noticed that there was a large electrolytic mounted 
under the chassis that I thought looked a bit out of place. After 
digging into it a bit more, It became obvious it was replacing one of 
the can capacitors. So, this got me to thinking that maybe the can cap 
is starting to slowly fail and therefore possibly this is my issue with 
the distorted cw signals. SSB signals sound good. I have made a bunch of 
resistance and voltage measurements (except at this can cap area) but 
have not found a spot that is looking really bad. So, any ideas?
