• WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
    Building, troubleshooting and testing of these amplifiers should only be
    performed by someone who is thoroughly familiar with
    the safety precautions around high voltages.

Hammond 125ese upgrade, need help.

Jensen p12s is extrended range speaker from 50´s, i don´t know response curve.
"Extended" means a bump at 5kHz-6kHz, which is "high" for a Twelve.

NOT "full-range" without a tweeter.

Put any decent 2-way speaker on that amp. 15KHz is plenty for cymbal, and my one experiment with 125ESE did not show a real droop at 15KHz.
