  • Removing__speaker 0-4-0 Porter cab

    Hi guys,

    I decided to take my first steps into On30 and recently bought a 0-4-0 Porter with DCC Sound from The Favorite Spot. I would like to replace the existing cab with a different one ... either lasercut or build one myself, but noticed that the small speaker/exciter seems to be connected directly to the existing cab.

    Is it possible to remove the speaker/exciter from the and leave the cables intact? If so, how can it be done?

    Cheers,

    Jeroen

    Jeroen -

    You can carefully remove the exciter from the cab.

    The problem is that when you go to install it back

    the quality of sound will b e greatly reduced. Other

    modelers have done this, but have replaced the exciter

    with a regular speaker. Not writen in stone, just trying

    to h elp youy decide.....;-)

      Would a replacement exciter be an idea? Noticed that it is referenced as SPKER# 10080 on the parts sheet, but I can not find it at Bachmann.

      Am thinking abou an open cab ... something like the one below (although this one is not narrow gauge):



      The lower part of this open cab should have about the same height as the lower part of the original cab. Would be great to be able to use an exciter with the same dimensions. Do you have any suggestions?

      Cheers,

      Jeroen

        Jeroen - You can search for "exciters" online.....

        I don't know about over where you live, but they are

        readily available at several places here in the US.

        Try Google for www.partsexpress.com

        I think that is where I found mine.

        Good luck!

          Thanks, I'll have a look around. Looks like the exciter in the Porter is about 20 mm in diameter. Have not been able to find one that small yet.

          Cheers,

            Jereon, the exciter can be pried off, but as Bill said, when re-attaching, the wrong glue can hinder the sound transmission.

            I know Verne used Aileene's Tacky Glue which has a flexible content to it (rubbery?)

            I would suggest a CA type (super glue) that is thin enough to allow good contact with your new cab roof. At least try it out. You will have the same problem attaching a new one also.

              Yep, that's true ... no difference there ...

              Bumped into the Zimo and CT "Sugar Cubes" on the web:

              http://www.sbs4dcc.com/tutorialstips...espeakers.html

              They look like an interesting solution. The article shows a video with two of them installed in parallel in an On3 Shay and the sound seems to be quite good. The size of one speaker (incl. the sound chamber)is 15 mm x 11 mm x 11 mm.

              As they are fairly cheap in this side of the Atlantic, I am thinking about installin two of them in the new cab.

              Anybody any experience with these?

              Cheers,

              Jeroen

                Never heard of the sugar cubes but sure sound like a good solution. The article said one was sufficient for good sound.

                Try it out and let us know. I saved the link.

                  Ordered a couple of them already and they are even thinner as mentioned previously... 8 mm instead of 11 mm.
