Used to sell CJ. It has a house sound to be sure. Repair is an option. Because of its vintage, I would go newer at least. Manley Jumbo Shrimp used. Think you would find more energy, detail, lower noise floor and improved soundstage. Less tubey than CJ. That might not be what you are looking for.
Even though you didn't ask, not a fan of the MIT interconnects. Mogami or Signal Cable silver would definitely open up things. Good hunting.
