  • Peavey CS800 transistor subs

    Got a CS800 with blown pre-drivers (7204 and 7205) Peavey subs are MPS-U10 and U60, but I can not cross to ON-Semi numbers! Does anyone know of subs for these?

    MPSU10 and MPSU60 are already industry numbers. As far as I know, On Semi has not made those MPSU series for many years.

    You have a CS800X don't you?

    I have seen people use MPSW42/W92

    WHen I need those I cruise my transistor collection to see what might work

      Yes, the MPSW42/W92 are good subs.
      If the transistor gets rather warm, you may want to consider purchasing the clip on heat sink.

        MPSU10 and MPSU60

        I have a MOTHER-LOAD of those parts... somewhere. I think they are near the top of the pile.

          I believe it is an 800c version.
          That's a to92 package!
          Seems kind of small but the specs check out!!

            How about mpsa42/ mpsa92?

              OK, I'll get on the CS800C drawing.

              MPSW42 is a larger TO92 case. MPSA are the regular TO92 size.

                MPSW42 and 92 are obsolete can also be hard to find. I wouldn't trust ebay type chinese sources, anyone have a good source?

                  MPSW42/92 300v 500ma 1W

                  I have 8 of each right here on my desk.


                  There I just held them up to my screen.

                      Enzo, What is your thought on MJE15034G and MJE15035?

                        Would probably work. I like that series and use them in several things. They would be overkill for that spot, but overkill doesn't mean it won't work.

                        As always make sure the E_B_C legs go in the right holes.

                          As always on subs! At least I can source these transistors!
