bridging tube amps for mono

so are you saying that i shouldn't get another auricle and bridge it.... ;-)

shaky understanding of circuits... why will a bridged amp see a lower impedance load? it's not the load that's changing is it?

Blakeaudio...One way to think about why the amp sees lower impedance is...when operating normally (not bridged) the amp is driving current through the speaker to ground. However, when bridged, the amp is trying to drive current, not just to ground, but against the output of another amp which is "pushing back".

PP stereo tube amp is possible to turn onto a full-function mono amplifier by connecting further in-parallel push and pull tubes between the channels and usning only one output transformer. That's how it's done in BAT tube amps. Just make shure the output transformer has enough of rated power which is in the most cases.
