[Amps] preparing unsed gi7b:s?

[Glen Zook]

I only ran my new GI-7bT tubes for a few hours on just the heater before applying high voltage.  They are working fine in my home-brew 160-meter amplifier.

Hi Forum,

What are you guys doing to prepare GI7b:s for first time use? I recall playing with one some years ago and I don't remember doing anything special apart from running it on filament for a day before applying HV.
What do you recommend?
