Hi all. Though I would post this interesting schematic of the MS 30L. Comes under MS77 now, but it is the same circuit. Notice the dual phase splitter. This circuit was one of the last British designs using valves. I have, of course, changed the coupling caps to Supremes (0.22uF). Sounds great, but I am up for some experimentation.

I love electronics and audio gear. I have a Yaqin MS 30L amp that sounds good to me. I wonder if anyone else has this amp?
