Hi, I'm selling my EC Studio Jr (230), purchased last year. This is the 300B version with feedback, the same version Marv recommended here. https://www.superbestaudiofriends.org/index.php?threads/ec-studio-junior-not-af.7527/#post-247872 In addition to everything that was originally included, the following are extra tubes: EML 300B-Mesh (pair, cleaner sound) - worth $760 JJ 300B (pair, lusher sound) - worth $300 Western Electric 2C51/396A (pair, but you need only one) - worth $150 Unlike a regular SJR where the tube sockets are oriented so that the tube logo faces backward, I asked Craig to build it so that the tube sockets are oriented forward. As you can see in the photo above, the EML logo is visible from the front. This is purely aesthetic. I'm selling everything for $2300 (Randos), or $2200 (Friends and Contributors), net to me. Please PM if interested.
