Haven't felt a need. What my slightly-modified jvm can't tune (very little
it can't) my 4229-L-network-and-dual-core-balun handles nicely.
That being said I did just recently popped for a used dual differential cap
to further expand on the concept (as laid out by Sevick, SK, and expanded on
by Rick) without butchering an original JVM...

Paul,
Why the need for a rotating turret? Wouldn't switching taps accomplish the
same thing? Cliplead taps on the coil have been a staple of link coupled
systems since the early days of ham radio, and it seems to me that one could
locate the optimum taps for each band and then use relays to switch them.
Doing it that way shouldn't be any more complex than a typical autotuner is.
