Here is a short video of my 90+ year Crosley Pup ,one tube radio. The tube is a UX201A. I'm using a 6 volt lantern battery for the filament, and Hewlett Packard variable voltage B+ supply, set at 45 volts for the plate. Instead of headphones, I use a pair of computer speakers. The antenna is my 40/75 meter inverted vee.
