Greetings all, Thank you for all of your informative posts. I'm building a modest collection of 6SN7 and related tubes as drivers in my setup, and hope to be able to contribute to this forum soon. Recently, I've been looking into getting a better Renter's Insurance policy, one that will cover all of the expensive audio gear, and ran into the fact that old-stock vacuum tubes fall into a different category, such as "collectibles" or "antiques" (as compared to current-production tubes, which could simply be repurchased at market value in the event of a loss). State Farm wants me to have an appraiser declare a value for all of my old-stock tubes, but I've never heard of an appraiser doing such a thing with vacuum tubes. I had thought that my receipts for whatever I paid for them (AudiogoN, Brent Jessee, eBay etc.) would have to serve, but State Farm may not accept that. Does anyone have any advice/experience/input on insuring old tubes (and/or expensive electronics as a whole)? Sorry if I'm posting this in the wrong thread, but of all the vacuum tube threads from all of the online organizations that I frequent, this is the foremost one!
