Overview:
To power a vacuum tube hearing aid, two batteries were needed: an ‘A’ battery to warm the filament in the vacuum tube and a ‘B’ battery ...to amplify the sound. The batteries were at least as large as the other components of the hearing aid and weighed up to 2.5 pounds. Users wore batteries in cumbersome battery holders under their clothes or in pockets with straps, and multiple thick cords connected the batteries to the earpiece and microphone/amplifier unit.
