You are way ahead of me...that's for sure!......the TD62083 drivers are an interesting device. Toshiba makes them I believe...this is the first time I have seen them in a nixie clock but it sure is a good way of conserving space for driving the tubes....Mr. Forbes you have just planted a seed in my brain that may start growing soon......My idea of an encapsulated brick clock is starting to take form....thanks...
