Need Audio Tech who knows tubes - Chicago area
Hello Friends - I own a Kondo Japan KSL Neiro 2A3 amp. An output tube recently went out and I will replace all four tubes. I've done some research and will probably purchase Emission Labs tubes. I have learned they need to be very finely matched to meet the needs of this particular amplifier. The tube matching is done by the EL by "gridding to the heater voltage" of the amp. Can anyone recommend a Chicago area audio technician/service proficient with SET tube amplifiers who can measure the heater voltage of my amplifier? I live in the Chicago northern suburbs. Thank you.
