[Boatanchors] HRO-60 repairs

I many time cut out the old part and then put some hooks in the remaining 
intact wires.  then I cut the new parts leads to fit and make some loops in 
the parts wiring.  I then hook the loops together and solder.  This way, you 
don't hook up the part to a wrong place and also don't disturb other wiring 
going to the same point of contact.

When the old part can be totally removed without affecting other components 
I do this too.  You just need to use common sence as to what technique is 
best for a particular application.

I think it is bunk to have to totally remove a component's leads when 
restoring an old radio.  What I described above has never failed me nor does 
it look bad and it certainly at times helped preserve some other components 
from being destroyed when replacing a part.
