caravan123, i remember some of your ads a year or so ago and less, a Jadis Ja800? I think at one time you had them for $10k? I almost hocked my car to come up with cash and the ad disappeared within an hour. If you are selling tube amps which use 30+ output tubes then yes I believe there is a very limited market regardless of price. I personally don't have the time/desire/paitience to monitor, find/buy that amount of tubes......unless of course you would sell the JA800 for 5k :)!
