It was good to meet you at Amiga30UK Paul.
It was good to meet you too mate. I had no idea until now that you're the chap behind The Silicon Vault! I visited your site a few weeks ago and was very impressed. So that A600 you got signed by RJ and Dave P, that will be an exhibit then?
Regarding capacitors, providing the machine is not powered on (much from new) they shouldn't actually leak. Not that it matters much with those signatures on.
You're doing some sterling work there with Amiga preservation! Keep it up mate, and looking forward to meeting you again at a future Amiga show.
