Remember-- the harder you load the output tube (up to a reasonable
point), the more IMMEDIATE the sound gets-- the more detailed, deep and
structured. WE LIKE THAT. You also get "more" power out, and more
measured "distortion".
What happens with easier loading? MUCH lower measured distortion AT FULL
POWER. Does this help sonically? Not really-- not ordinarily... because
ordinarily we ARE NOT running full power-- full power measurements, while
interesting, really have nothing to do with musical integrity..... what
we normally appreciate in music.
Does Dennis Fraker have any recommendations for the correct harmonic profile for a SE DC 2A3 amp?
If I set up my FFT with a 1KHz sine wave input, what power output should I be measuring?
How far below the fundamental should each harmonic be in dB's?
This is for his 2.5K plate load recommendation at reduced bias current.
