[Hammarlund] REPLACING COMPONENTS

[Patrick]

A good observation.

I simply snip out the old cap leaving plenty of leads. I then turn a 
small eyelet in the old lead and insert the lead from the new cap into 
the eyelet and solder. There is nothing electrically wrong with this method.

Removing the solder and old lead from (for instance) a tube socket is 
asking for a damaged socket.

If the goal was a museum piece instead of a reasonably working device 
I'd leave everything alone (and not plug it in).

To each his own but if the wanted result is working equipment with 
reasonable aesthetics the snip and replace method is ideal.

I do have a different take on the guys who restuff electrolytics.  There 
is sometimes a problem physically locating multiple electrolytics under 
a chassis that restuffing cures.
