Yes I definitely plan to restore one myself sometime! I would do it now, but I currently own this beauty (black version) from Yamaha that has a nice vintage look.
I am also almost done with my back loaded horn project! Here's a pic of a box I just sealed up today and need to finish with some additional coats of Tung Oil. Apologies for the low lighting and quality, was taken with my phone and ceiling light off. The second pic is a rough estimate of what it will look like once complete (different driver, but same tweeter included). I can't wait!
Yeah thats a lovely Yam! And nice work on the speakers, looking very smart indeed.
