      TM808 coils

      Hello dear Gurus!

      First of all, thank you very much for all the work in the Project tm808. I love how easily you can find details on everything in this forum.
      I read almost everything about TM808, but there are still a few ambiguities...
      i know its just a few little parts, but im a total beginner of that. Can anybody give me the schematic of these two parts? And where do i have to connect them on the mainboard?
      Has anyone built the two big coils for TM808 sucessfully? Are there specs for core thickness (i guess material is Aluminium) windings, wire size and diameter of coils? Or are there any instructions for building the coils step by step, that ive overlooked?

      Would be great, if somebody could help me.
      Thank in advance.

        ok now, ive just read, the wire diameter is 0,75mm. Right? (my english is not the best, just want to avoid misunderstandings)

          What is the polarity of the red lead to the JACK plug?
          In side or out side?

              Hi kt315, any idea about the values of the parts on the small PCB's or did I missed a thread on that subject?

                hi marcus, you are due missed sleeping away... I shared 2 or 3 times _all info_on whites_ in another thread, esspecialy done by me for this goal.
                all sketches, all schematics, all layouts. including a data on coils of TM-808.
                THIS ALL INFO IS NOT MINE AS I AM NOT A SOURCE, I ONLY TAKE IT FROM THIS FORUM AND KEEP THAT AT A HARD DISC.

                  Hi kt315

                  thx for your reply.
                  For a rookie as myself it's difficult to find your way in the forum and all the theads.
                  I guess it's somethimes frustrating for you when a rookie again asks you the same question that you've answerd a few times.
                  So I'm sorry for that !
