Guns on RPTV (1 Viewer)

[Bruce Springs]

How often, if at all do the guns on a RPTV have to be realigned or readjusted? If they do, how is this done? Thanks for your help.

You probably mean convergence. This should be done periodically, and is mainly an electronic adjustment, but certainly proper mechanical setup and focus are important, though this is usually less likely to change with time than the electronic stability.
