Yairi DY76 string recommendation

[BuzzBates]

Hi all, does anyone know what strings (brand and gauge) would have come on the late 70's K. Yairi 12 string guitars? We just bought a sweet 1978 DY76 12 string. It came with GHS Custom Shop effectively 10-49 (10/10 13/13 23/09 29/11 39/15 49/23) We like them fine and have got a second set with the guitar but I'm wondering what brand and gauge it came with.

I use John Pearse 600l p/b's on my DY-71. Might want to give them a try.

In the late seventies there were few choices.
I would hit www.juststrings.com or one of the other string retailers and pick up a variety of strings to try. At least a set of 80/20's and a set of Phosphor bronze....
