I believe that you will find that the word "robust" adequately describes your new tuner. When they made stuff that said 3K in the old days, they meant it. If you look inside, you'll probably find silver switches and rotary coil. You'll also probably find ceramic forms for everything, instead of fiberglass or plexiglass. If I were you, I'd just run the thing and not worry about it. BTW, I got the other Dentron that was on auction at the same time. That funky handle on the rotary coil is gonna look nice next to my KWM-2A. Still waiting on both the tuner and my call letters. Can't wait for either!
