I heard of the power reduced versions in the australian site (about the
FL-10/40), but elsewere (rigpix database for instance) it's indicated as a
75W input. Now I'm sending mail to everyone I could find in Internet that
seems to have a FL-50B. Who has used it, must know at least the power
output! Hope someone will reply.

Anyway, if that's the case, it's a good and a bad news at the same time: I
worked for almost a week in troubleshooting a perfectly working transmitter,
I bought some spare tubes and a tube checker, etc...
But I discovered again the vacuum tube world so much in this week!
....that I decided to seek more old radio and I posted an announce for
buying an Hallicrafters SX-88 and/or a SX-28!!!

And again, I got acquainted with this newsgroup
