Toshiba SA-7150

Digital Synthesizer Stereo Receiver

Description

In the Toshiba SA-7150 there is no tuning dial or knob; the fully automatic quartz frequency synthesizer system does away with these because there's simply no more accurate nor any more stable way of tuning than this.

The precision and quality start at the very beginning with the selection of the quartz crystal itself.

Other features of the SA-7150 include:

VCO phase locked loop (PLL) using three Toshiba ICs

Accurate and stable reference frequencies

Precision/automatic control

Microprocessor tuning control

Narrow/wide bandwidth selection option

Newly improved quadrature phase detector

PLL multiplex IC with auto pilot canceller

Super power toroidal transformer dedicated to output power

Separate power transformer for preamp and tuner circuits

Direct common connections and double thickness copper pc boards

Brute force OCL power stages

Cascade and emitter followers driving current mirror stages

Fully protected with double contact relays

Built in dolby FM reception circuit sections
