[time-nuts] Install a 5061A/B tube into a 5071A!

Well I thought that would get your attention! It's not quite as simple as that, however it CAN be done. First you need a good "mini" tube scavenged out of a 5061A/B. These smaller diameter tubes HP made for 5061A/B replacements are essentially a 5071A tube with different connectors. Then you
