This was one of the first digital synthesized tuner. It was constructed with a little help from Pioneer. The massive 19 "aluminum front was a typical feature of the Phase Linear series. It looks very good to the famous amp line from Bob Carvers Phase Linear line.
The first stereo receiver with quartz-synchronization for the FM band. Even the previous TX-4500 was a successful ONKYO upper middle class. Here the design has been optimized. For the display scale real thick glass is used. An expression of timeless elegance, in my opinion. A heavy receiver with high power for 3 pairs of speakers. 65 watt per channel.
A heavy Marantz quadro receiver. It sounds so well in stereo also.
70 watt per channel x2
25 watt per channel x4
1976 A small receiver from the mid-seventies Technics series. 45 watt per channel
These old Technics units from the mid-70s are really underrated. I had one,i sold later, Really nice sounding unit and looked very good in an understated kind of way.
The state of the art preamp from the Sansui "Definition Series" CA-3000. Massive construction and selected components made this unit to legend. It sounds superb until today.
Sansui's history-making 4-Channel Synthesizer Decoder QS-1, the ingenious yet inexpensive Sansui instrument that magically transforms two channel stereo into a live four channel sound field. Two power amps needed. It's sounds like the classic receivers QRX-9001, QRX-7500. This unit is in best condition after restauration.
