Hi there,
I´m a proud owner of an old Drake L7 amplifier. It has been working out
flawsely for 6 years here at my shack.
Just wondering what would be a reasonable period of time to heat it up before
applying any load. Since first day I got this amp, I let it standing by for 5
to 10 minutes and then switch it for low voltage (1800V) and run it for a
couple of hours at low power (500 wts) before take it to its full output limit
(1Kw). No problems so far but a few days ago I talked to a fellow ham with same
amp who advice me to let the amp heating up for an hour or so. For me this
would be so much time but I haven´t found any details about this on the manual
that´s what I would like to ask here if you think I´m reducing the life of my
3-500s. Thanks and 73s!
