Wow, another engaging, informative and thoroughly enjoyable resto saga by Phil. Good to learn some of the arcana behind the Capehart-Farnsworth symbiosis. It's a privilege to have played a small part in helping the project along, and to have vicariously "worked on" an actual set bearing some of old Philo's 'novel' pre-standardization circuit features. Interestingly, just an easy walk from an apt. building i manage is Philo's old lab at 202 Green Street, SF.
