I had an RM 10 mk ll. I wanted more power and looked for a year for another amp so I could make a mono block. Never found one. Sold mine exactly 3 years ago. Looked a few times, but I’ve never seen another one.
it’s a really nice instrument! Really, Good luck finding one. I have a quad of exquisite el84 from Brent Jesse. I would be happy to let go of them, but they aren’t cheap. PM me.
