Product code: Vacuum Tube Pay orders Telephone Price Minute Output Bumblebee Caps AP5488 AP4638 units
These modules are missing three total vacuum tubes. Two 12AX7 and one 12AT7. I'm not sure what they did, but one has a huge dial that selects a resistance that apparently encoded the price per minute, of a phone call! The other one is loaded with Sprague bumblebee orders capacitors. Untested. You get both.
