The damper hangs off the SG-613, usually on a terminal board, along with two caps - typcially a 330pf and a .014uf to .018uf Blue Epoxy Dipped cap. The blue cap tunes the horizontal to the flyback/deflection circuit, kind of analogous to the safety caps in US made sets. They are obsolete - but a good 715P or 716P (polypropylene film/foil) Orange Drop will also do.
Damper diode part number is SID30-15 on your set - Sony recommends replacement GH3F, Sony Part number 8-719-305-15, also the newer RS3FS diode, Sony Part number 8-719-312-71.
ECG/NTE 506's WON"T work. Save your money.
If your SG-613 is good, then I'd recommend finding and replacing all Electrolytics in the Pwr supply and Horizontal - typically on the "VH" board. The 4.7uF 160V and 250V caps cause the most grief.
