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.

Subject: [Amps] preparing unsed gi7b:s?
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?
