Well still trying to find an RC-70 or 71 for the 22-4...appreciate all or your folks help. Just getting some old stuff out of the closet and rigged-up, and aquiring some other gear (wife if starting to go nuts, sees the $$ but only a mess in the "music room" so far!). Think I'm in trouble on the 22-4 head(s). I'm in Kansas City...anyone know of a decent R2R shop in the area?? If 22-4 is shot maybe will be looking for a Tascam 8-trk?? What would be your choice, make/model, on the 8-trks?? Were there ever rack ears made or still available for the 22-2 and 22-4?? Lot's of questions and maybe will start to see a glimmer of light at the end of the tunnel. Thanks again for any help/suggestions...always appreciated. RB
