Description
10k/10k+10k (10K/40KCT) input transformer with two identical outputs for driving a balanced (push-pull) amplifier. Two chamber bobbin ensures 100% amplitude and phase balance over the full bandwidth. Replacement transformer for Triad HS-29 with improved performance. Zobel network not normally required. May be used in reverse for stereo to mono combination. Ideal for the interstage transformer on the Pultec EPQ-1A giving improved performance relative to Sowter type 9330. May be used as a high impedance spliter or combiner. Ideal for combining two stereo signals to feed a mono amplifier. Max level +31 dBu Mumetal can. Needs a small modification to fit Drip chassis. Please ask for details. Can be used to replace obsolete type 3276 by connecting secondary windings in parallel.
