[Heathkit] need parts for sb-303

[yash at aol.com]

         I have a 303 with 5 bad coils on the het osc board,anyone have the coils ? part # is 40-978 to 40- 982. the slugs are either cracked or frozen. Would also be interested in the whole HET-OSC board its # is 85-347. Maybe these coils were used on another heath rig? Hate to scrap such a beautiful rig for 5 little parts.would be greatful for any info,parts,boards or a clew where to look.
thanks
