Japanese drama OSTs – the akai collection

Hello, i’m looking for some OSTs to famous Japanese dramas in the 70s, i think every Japanese must know them, i mean who doesn’t know Akai Gekiryu 1976, Akai Giwaku 1977 and some old akai drama series from 1974 that Momoe Yamaguchi acted in and sung the titles music, any way, if you asked about the composers i forgot some but i’ll never forget Shunsuke Kikuchi’s Akai Gekiryu music from 1976, i heard the music in youtube and seems very romantic and dramatic, it’s said that Kentaro Haneda played the piano pieces in it, the OST is found in some rare vinyl LP that i can’t purchase, any one has it please?
