You need a PCM adapter of the same general type that the tape was recorded with. That would include the Sony PCM-F1, PCM-701, PCM-501, PC-601, or certain other units marketed under the Sansui and Nakamichi brand names. The most useful of these was the PCM-601 since it had a tracking indicator and a variable tracking control that the other models didn't have. There were NTSC (= US/Japan) and PAL/SECAM (= Western and central Europe) versions of those adapters, so the adapter you use must match the video format of the recording and of the video player.
Most VCRs have dropout compensation built in. It's better if there's some way to turn that off (it interferes with the error correction ability of the adapter), although this was provided only on certain Beta VCRs of the time as far as I'm aware.
If these are S-VHS tapes then you can't use a Beta player (the two systems are physically incompatible); you need a VHS player with S-VHS playback capability.
Assuming that these tapes were made in the 1980s when the system was in vogue, they will probably have unrecoverable dropouts now, which will probably cause moments of silence during the music. It may help if these recordings really were made as S-VHS rather than conventional VHS (although the fact that a tape cassette says "S-VHS" doesn't absolutely guarantee that the recording on it is S-VHS).
Let me know if you have other questions about this--I used the format for live concert recording (and even live recording for CD release) for several years.
