The audio/control head only is suspect and as the vcr is old the spares will be difficult. SEME in the u.k still list it but may need to have a business account.
Have a look and enter the site as a guest although a price will not be quoted.
Companies I used to deal with are:
C.P.C, Willowvale electronics, seme, charles hyde and son, Nikko electronics along with the various manufacturers.
Matsui are a curry's brand and and Mastercare serviced the brand but although not certain may now be partmaster supplying the spares.
