Running a radio without speakers
I had an old amp that would spark across the spark gap with no load
connected. But whats the mechanism for that? No load cant take any Vs
higher than normal run voltage, unless theres some kind of LC thing
going on in the op tf, and no load means no damping.
The voltage can rise to the point that the insulation in the output
transformer windings breaks down and arcs over, destroying the transformer.
