I just finished building my tube strain gauge preamp with EQ inside.
It's sound very good and made me feel happy so much.
But I need to measure frequency response of my preamp for adjust EQ to become flat.
Could anyone suggest me about program and equipment for measuring?
Thanks & regards,
You need a test record with a frequency sweep from aprox 20 to aprox 20000Hz, or a pink noise track on it.
Then you can record the audio to a PC and do a spectrum analysis on it, for example using audacity.
