    John,I am using the one with the RTC Ic and crystal, I built two of them and both are inaccurate. Do you have a later version and if so could you supply me the link.Will it fit in the same space?RegardsJim

    IV-11 VFD Tube Clock Assembly Guide

    HiI am unsure if you understood my issue. The fourth tube from the left displays a capital P at all times which makes the display impossible to read and set.(I have attached a photo of a sketch to better explain the issue).I did not understand what you meant by "could be a problem from the IC connect dock"Could you let me know it you will send the chip with the latest software and a replacement tube if that is the issue.As i said I am impressed with the kit if only i can resolve these issues.Kind regards

    The clock kit was easy to construct with a quality pcb and all components. I have however an issue with one of the tubes (the fourth from the left displays a capital "P" when turned on and therefore the only time it is correct is when an 8 is needed.I have swapped the IC's to no avail, and I suspect the tube is faulty or a program problem.Also the chip supplied was programmed with the original data and does not have the ability to change the date, temperature or hour modes.a couple of questions;Can the full stops be disabled except in the temperature modeWhat do the "PP" letters represent in the temperature mode and the two "-" in the alarm mode.If this can be resolved I will order another kit for a friendRegardsJim
