Thanks Jim! I am working on a Hammarlund HQ-180 and discovered that T-10 in 
the 60 KHz chain was frozen solid. Couldn't budge the slug. In case you 
aren't familiar with T-10 the under chassis end is buried deep beneath a 
multi deck rotary switch and it would be a horrendous job to remove the 
transformer and even to just remove the can. It had to be repaired from the 
top! So taking a tip from you, I carefully drilled out the top of the can to 
just over 1/4" dia. then broke up and removed the frozen core. I used a 
small parts magnet to extract the pieces. The to be sure that the new slug 
didn't get stuck in some damaged threads, I ran a 1/4 - 28 tap into the core 
to clean up the threads. The new slug went in smooth and easy. Viola! just 
like new.
