Ged - Later, after you have your CTH working again, you might find it a bit funny reading runeight's sig & the quote above
Note that I too broke one of my CTHs causing a short while taking measurements in the output buffer area. Searching for CTH trouble-shooting posts by holland, runeight, etc & the info here should narrow down the problem. IIRC in my case I replaced all the BC devices in OB & that fixed it.
Back in the proto days I'd a lot of practice pulling & replacing TO92s
Using PCB vise, used a solder blob floated among 3 pins, pulled 'em then used solder vac to remove excess. Desoldering braid might sub/help too.
Good luck. You'll get a bit more DIY, learning & practice than you expected but the end result will be worth it.
