Wouldn't the new subrx also have to have the extra preamp to match the
one in the KXV3B?

I believe it has to do with reducing low frequency noise on the 8 volt
line.
The addition of the capacitor was mentioned by Eric at the FDIM when the
K3S was introduced.
The new synthesizers made that lower frequency operation possible, and I
assume that during testing, the noise was noticed.

OK Don, I'll bite: What does a "220uF Solid Polymer Electrolytic
Capacitor on the output of the 8 volt regulator" have to do with an
"extension of the K3 tuning range to 100 KHz?" Voltage regulators are
usually found at the far end of the circuit from frequency determining
components. Enquiring minds would like to know. [:-)
