Turntable Teppaz Transit - Electronic Schematic

Complete and detailed electronic schematic for the TEPPAZ Transit turntable amplifier system. This technical documentation presents the comprehensive circuit architecture of the Transit model, with precise component identification and interconnection layout. The schematic encompasses the input stage featuring coupling capacitors (150 µF, 1000 µF), biasing resistors (220 kΩ, 470 kΩ, 10 kΩ), and a preamplifier section utilizing 0C70 and 0C78 tubes. The main power amplification section includes dual output stages with 0C74 tubes, output transformer, and automatic shutdown circuitry. The document presents the complete power supply section with 500 µF reservoir capacitor and dedicated bias circuits. A separate section illustrates the turntable motor circuit incorporating clutch mechanism, variable power adjustment with temperature compensation, and coupling capacitors (4700 µF). Critical component values are clearly specified: load resistances (630 Ω, 4.7 kΩ, 56 Ω), filter and coupling capacitors, providing technicians with precise values necessary for accurate repairs and restorations. An indispensable reference for maintenance work or restoration projects on this iconic model.
