The TC-K 611 S is similar in design to the Sony TC-K 707 ES (sold in USA, better sound heads) and Sony TC-K 71 1 S (has closed dual-capstan tape run). The TC-K 611 S shares the Service Manual with you.
In the Sony TC-K 611 S , the dual-capstan drive was omitted compared to the previous model of the 6-series, the TC-K 690 (sold in 1992-93) . This was continued by the TC-K 711 S (newly created 7 series).
The successor model Sony TC-K 615 S has a few comfort functions less. For example, the adjustable headphone output has disappeared.
