I had my Drake T-4XB running the last couple days. I went out of the room for a while
and when I came back in both of the bulbs for the vfo and s meter were out. I checked
the one for the vfo by putting into the R-4B and it lit up fine. I did not pull the
one from the s meter as it is difficult to remove. Any ideas what would cause them
both to go out like that or what to check first? Thanks. --- Steve KK9ZZ
