Downright scary when you fire one up.  ("Omigosh!  What's that thing doing 
to my radio!  So much for that RF deck alignment I just did!")

If you want to get an idea, just remove either or both of the MC and KC 
knobs from your R-390A or R-390, chuck up one of the shafts in your old 3/8" 
Black 'n Decker variable speed drill, and give 'er a spin.

Barry - Dittos for the R-389 motor tuning also. I have used the motor tuning 
- once - on an R-389 and I just about cringed at the way the main tuning dial 
spun around so fast I thought it was going to break something inside. I am 
sure it is rugged enough to use a time or two but after seeing how fast it spun 
things around I wouldn't want to use it again unless maybe for a special 
occasion or to demonstrate to someone else how it works and then only for a second 
or two and only if I knew everything was perfectly lubricated inside.  73 Todd
