  • Sunn 200S

    Sorry if this is the wrong place to post this..looking for a 200S schematic with solid state rectification. Are the filter caps the same as the tube rectified version?

    Maybe the GZ34 was removed and diodes fitted in place.
    This amplifier is from the Dynakit Mk3 range (from memory) and uses a GZ34, two KT88s as output and a couple of phase splitter/ driver valves depending on who built it.
    I would think the capacitors are the same value as to increase them will possibly put a strain on to the transformers HT winding.

    If you can't fix it, I probably can.

      No this amp has no hole drilled in chassis for the rectifier tube. Just want to know if there was additional filtering for the diode version??

        Well, here are the schematics:

        The 30uF is in a different spot, but that makes no difference.

          As far as I know, that SS version is somebody's build: https://el34world.com/Forum/index.ph...5718#msg225718
