Bryant Unlimited kindly donated a drum of double-screened video coax and their remaining stock of crimp PL259 connectors for our Vivat project.

This weekend I’ve been working on the ‘final’ Vivat PWM – this is the ‘US spec’ one that we changed the mains transformer on. The electrolytic capacitors are stamped ‘1953’, so it’s a good early one from MkII days.
