Re: 2.5ohm loudspeaker
Er, what's wrong with a more readily found 3 ohm unit?

Re: 2.5ohm loudspeaker
It probably is a 3 ohm unit. The DC resistance of the coil will measure about 2.5 ohms. 3 ohms refers to the impedance (AC resistance) measured at 1khz.

Re: 2.5ohm loudspeaker
Given the variations of impedance a loudspeaker gives across the audio band and that valve amplifiers are more tolerant of lower impedances than of higher impedances, 3 Ohms ought to be fine in most instances.
2.5 ohms may be a clue as to the use. I remember that AR88 documentation calls up the use of a 2.5 Ohm speaker. David
