1/2 the power is only a 3 dB difference, not much. The amps input sensitivity may also change affecting the volume level. The real question is which mode do you like the sound of better. If you can't tell a difference between the two just keep it in tetrode mode.
Should the sound level in Triode mode be lower than in Tetrode
I've just got Manley Lab Series 100 vacuum tube monoblocks. And I am a bit confused what to expect from TRIODE / TETRODE modes. The user manual says that:
"...When the switch is in the upper position, the amplifier is in TRIODE mode which will produce half the power of TETRODE operation."
In the same user manual under the Specifications section I find that the Output Power for:
"...When the switch is in the upper position, the amplifier is in TRIODE mode which will produce half the power of TETRODE operation."
In the same user manual under the Specifications section I find that the Output Power for:
TETRODE: 135Watts (@1.5% THD 5 ohm load)
TRIODE: 65 Watts (@1.5% THD 5 ohm load)
I have been running a number of db level measuring tests by switching from TRIODE to TETRODE mode keeping the volume knob unchanged. But it appears that the sound volume remains exactly the same in both TRIODE and TETRODE modes. Shouldn't I expect the sound level in TRIODE mode to be half of what in TETRODE mode?
