I rebuilt a model 20 about 10 years ago. In my instance the can, when unbolted, had enough slack to pull it far enough away to unsolder the wiring inside the can. I propped my cap block over a large metal coffee can then put it about 18 inches in front of my garage torpedo heater. The guts fell out in one piece after about 5 minutes. A heat gun can also be used, but the heater is quicker. Take care, and BE HEALTHY! Gary

P.S. I re-built the can to original specs as close as possible using film caps rated 630 volt.
