Some more info on the twin mini-system:
The supply is drawing 33W at the wall plug. DC input from the
variable SMPS to the inverter is 28W. The output of 20W stands.
I disconnected the earth lead from the junction at the bottom of
the two resonators and they do play together nicely. However, there
is, as the astute will have noticed, a small tuning imbalance and
that showed up as a slightly stronger output with the earth connected
and also a 1/2" arc from the centre-connected bases and the ground
lead. The coils were attaching at 4.5" about 1/4 of the time when I
set the system up this morning.
Onwards and upwards,
