I may be able to source a number of genuine Yamaha service manuals and the supplement for the GTS, part numbers 4BH-28197-20 and 4BH-28197-2A. Price for the pair would be around �25 plus postage, which in the UK would probably be around �5, depending on the quantity ordered. If anyone is interested in a set let me know off list at [EMAIL PROTECTED] and depending on the response I'll see what I can arrange.
Although this is aimed at UK listers, if anyone in the colonies or anywhere else is interested let me know and I'll try and find out what postage would be. Regards to all Doug L
