OK, I got the SET bug.
Today's the day I hook up my new SET 2A3c amp.
The amp is three watts per channel, well, four with 10% THD.
I'll be using it with some Apogee ribbons. The Apogee dips to one ohm resistance, and is 86dB 'sensitive.'
So, if 1 watt gives me 86 dB, but the amp output doubles its output with every halving of the resistance, then...
My four watt amp should give me 8 watts at four ohms, 16 watts at two ohms, and 32 watts at one ohm.
I should get 89 dB for two watts, 92dB for four watts, 95 dB for 8 watts, 98 dB for 16 watts, and 101 dB for those 32 SET watts into one ohm.
With the gentle clipping behavior of tubes, I should be able to rock the party!
Thank goodness for physics.
