Hey Saul. Just sent a little that I could spare, but hopefully, can send more later.
You may want to check out
http://audiokarma.org/forums/index.php just to get a feel for how they do things. It's one of my favorite forums for vintage audio. They even have a Yamaha section. Basically, they offer subscriptions, but it's voluntary. They have a "barter" section, where members can buy and sell their vintage audio equipment, but you can only see that section if you're a subscriber. Seems to work pretty well. I've been a subscriber for several years.
