[R-390] Standy or Off?

[charles bolland]

Hi all,

I've burnt out a couple of Ballast tubes over the months and I am a little
"gun" shy now.  I don't want to ware out other tubes in my set, so I am
wondering which will prolong the life of any tubes in my receiver best of
the three following options?

1. Completely off when not in use - thinking about turning the set on and
off all of the time.
2. Standby when not in use - thinking some tube still burning all of the
time.
3. On when not in use - thinking all of the tubes are hot all of the time.

Any comments will be appreciated.

Chuck
