Fifty bucks is a good price for a pair of finals for the FT101E. I replaced mine with a pair from Fair Radio, for 90 bucks, plus shipping!
You might also want to replace the driver, the 12BY7A. It can be found easily and isn't nearly as expensive.
Those sweep tubes require critical 'care and feeding.' You can destroy them in ten seconds. Literally. When you join the FT group, you will learn much about the tuning of that radio. With care, the tubes can last for years. But it takes true TLC and knowing at all times how to tune the rig and 'babying' those tubes during tune up.
The rig was very popular with CBers because it could be easily modified to operate on 11 meters. Many of those rigs were CB'ized." That is, driven hard and put up wet. When it says 40 watts AM output, it means no more than 40 watts AM output!! Not 80, not 100. Just 40. And better to run a bit less.
But the big problem comes in tuning. Inexperienced FT101E operators tend to tune slowly, double checking, and those tubes won't handle that!! I always advise anyone starting off with an FT101E to practice the tuning procedure with the power OFF. Run through it, as shown in the manual, several times, get the feel of the knobs, the sequence you will adjust them, and pretend you are seeing the meter readings you expect to see. Only after becoming familiar with tuning the rig power off, do you switch on the power and do it for real.
I also recommend, once doing it for real, doing it with very low drive, just a few milliamps of plate current above the idling bias. Do it the old way - dip the plate, starting with the Load control as minimum. Then increase the drive slowly to get about 120 mils plate current, and redip. At that stage you can start to actually load the rig.
Follow the procedure in the manual, but do it quickly! And I recommend monitoring plate current as often as you can during tune-up.
They are good rigs.
So are the Drakes. I hope you get the Drakes on the air, as they are absolutely one of the best ham rigs ever built, some claim second to Collins, but I actually prefer (and so do many others) the Drakes over Collins.
Good luck, and welcome. Baby that FT101E and you will be a happy camper.
