Hey everyone, I finally got around to opening up this guy. How I came to have it is documented in another thread. https://www.tdpri.com/threads/first-things-to-do-when-servicing-a-vintage-amp.975472/ Anyway, it appears to have a stock Marsland speaker. I haven’t heard many good things but I’m going to hook up another head to it and see how it sounds. I’m guessing it’s 8 ohm impedance? I don’t see anywhere that it says for sure. The eyelet board is in need of replacing as it is very warped and damaged: And But it looks like it has been recapped, the OT looks to have been replaced. And a 3 prong plug has been installed. So most of my initial plans have been done to it, now I’m thinking of cleaning it up and making my own eyelet board to replace this one.
