    Try removing the 25uf bypass cap from the driver stage cathode.Will lower the gain some.

      6sj7 gain

      I play through an old Stromberg-Carlson AU-29 PA amp which uses a two 6SJ7s into a 6L6. It has the most crushing, milkshake thick distortion. I might have the schematic around...

        HELP

        I'm trying to build my first amp and I could use some help from some more experienced ppl.

        Im trying to build a 5c1, i dont care if its a darker sound, its also the simplest champ.

        I dont under stand what size choke transformer to use???

        what type on volume and on/off switch to use?


        ive been looking at transistors on the weber site:
        https://taweber.powweb.com/store/resord.htm

        Do I buy "25K Ohms, 1/2 watt" , what "watt" transistors do I buy??

        if the layout chart calls for a .02mfd 600 volts, do I buy a ".022uF, 630 volts"

          Hi, and welcome.

          Might I suggest you start a new thread for your project instead of adding it to this one. That way we won't wind up talking about two projects at the same time and getting all confused. At my age that happens easy.
