No frame\/weight\/shell modifications are needed! The factory PCB will need to be removed. Decoder installation can by simplified with a Nix Trainz Decoder Buddy and a 21-pin decoder, or you can hard-wire a decoder in. Board-style decoders will not work (Soundtraxx PNP, LokSound Direct), as they take up all of the space between the two weights and leave no room for the speaker.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eThe speaker comes fully assembled and tested.\u003c\/p\u003e","brand":"Scale Sound Systems","offers":[{"title":"Default Title","offer_id":49100273713460,"sku":"ALCL-3840-RC1","price":17.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0864\/8982\/5588\/files\/7e84c8_f244901fac764d1389a35545ed6116ed_mv2.avif?v=1776533327","url":"https:\/\/yankeedabbler.com\/products\/scale-sound-systems-alcl-3840-atlas-classic-master-early-gp38-40-ho-scale-alcl-3840-rc1","provider":"YankeeDabbler","version":"1.0","type":"link"}
