I have an Consonance opera tube amp. The amp uses KT88s in a push pull final stage with transformer output configuration. The amp has speaker connections for 4 ohm and 8 ohm but only a common negative for each channel. I was wondering if I could connect 4 speakers, two on each channel utilizing both + connections and the single common negative. I have both 8 ohm and 4 ohm speakers.
Thanks for your help - Jake
