I have a pair of Cryotone 300B-WC tubes for sale. They have about 1000 hours of use in my Decware SEWE300B.

These are excellent tubes. I prefer to use another tube type and have purchased a backup pair of those tubes, and have another pair of Sophia Electric tubes as further back up, and these will sit unused for a long time which they don't deserve.

These would be a pair of already broken in tubes that you won't have to wait about a month to receive from Wathen. 825 dollars including postage within the US. Please PM here or email me at lonjazz@yahoo.com if interested. Thanks!
