Re: [TCML] Tube coils structure
Hi John,
I now only have a single 833(C) and a single 833(A).
I have temporarily lashed the 833A in parallel with the
833C (you know I'm gonna use the C tube if I have a
choice ;^) just to see how well the extra tube would
share the load. It does indeed "spread the load". I am
assuming that a "push-pull" setup means the tubes are
wired in series rather than parallel?
