We repair senior transistor preamplifiers and tube preamplifiers of studio technology (low frequency-technics). Therefor please supply us if possible with a microphone capsule (i.e. entire microphone) and where applicable with PSU

Mainly the problem of a defect condenser microphone is a result of deterioration of the microphone transducer. Further possibilities of defects could be in the microphone preamplifier. We check preamps, measure noise and distortion factor together with repairing of transducer, we measure frequency response and if required replace components.
