The SRIII is a different breed of cat, and has indeed
suffered from abysmal quality control. I have yet to see one that is
properly calibrated, and the are definately cheaply built. The SR1 and SRII,
on the other hand, are virtually indestructible, and are not made with cheap
plastic nor with cheap third rate components. The only two times I have ever
seen a switch fail on an SRII are when the owner thereof decided to use
their fist to turn on the radio.. and have never seen a switch failure on an
SR1, which had a heavy metal built switch.

When did GE start using varactor tuning in the SR instead of a
mechanical variable capacitor?
